The Paramount 4K master is HEAVILY revisionist in that all of the effects and opticals were redone and tweaked with errors and issues. There has been grain management (moments of stagnating grain and haloing) and the encoding isn't great hence the typical Paramount noise in the image. (especially skies) The HDR is a bit bright in the highlights. The Blu-ray is showing its age but does not have any of these digital alterations. It is from the scan done by Laser Pacific and is the highest quality unaltered master we have. The DVD was done by Lowry Digital and had much scrubbing and processing of grain in addition to edge enhancement. The letterbox LaserDisc was the first widescreen release and is very good for its time. There was also a rare SVHS release using the letterbox LaserDisc master.
The 4K Blu-ray audio is seemingly an Atmos remix of the 5.1 found on the Blu-ray which itself is very similar to the DVD 5.1. All are presumably based on the 70mm Dolby six track mix. The Atmos is more processed and moves the sound around more so it is inferior to the older 5.1 iterations. On release, Last Crusade had Dolby 70mm with stereo surrounds, Dolby Stereo SR for 35mm and was mixed in a THX sound theater to ensure the ultimate in technical quality in 1989. The DVD was supposedly made from the 70mm mix and the Blu-ray 5.1 seems to bring that into lossless. This is unconfirmed but each seems to be a healthy and accurate version of the original audio. However, the LaserDisc despite only having matrix PCM stereo is punchier and livelier as a listening experience. Despite not being discrete it arguably sounds better than the 5.1 versions. Some who remember seeing each of the original release versions claim to remember the 35mm Dolby DR as sounding better than the 70mm Dolby.  This is a case where both sound great and it's up to fans to decide which they prefer. Both are essential for any Indy collection and the LaserDisc is very cheap. The VHS hifi seems to be the same 2.0 matrix with format differences so it can also be compared against the DVD and Blu-ray 5.1 versions.

The Paramount 4K master is HEAVILY revisionist in that all of the effects and opticals were redone and tweaked with errors and issues. There has been grain management (moments of stagnating grain and haloing) and the encoding isn't great hence the typical Paramount noise in the image. (especially skies) The HDR is a bit bright in the highlights. The color timing and Atmos remix are thankfully taming the excessively overdone terrible Blu-ray in those areas but neither is fully accurate. The Atmos remix sounds lifeless and essentially tames the crazy LFE of the Blu-ray remix that never stopped while also spreading the sound around overhead. The music is absolutely lifeless here. If it weren't for the visual changes it might be possible to regrade the picture master and just live with the encoding noise. As it is, purists will want the LaserDisc, DVD or Japan WOWOW broadcast of the Laser Pacific master which is the same master used for the awful Blu-ray just without the hideous color grading applied.
The DVD was handled by Lowry Digital and is overscrubbed like crazy plus had all sorts of DVD era edge enhancement and other issues. It instigated the digital changes of the boulder rod and snake reflection removals. The ONLY widescreen versions of the film without ANY changes are the 1992 LaserDisc and the 1999 final release VHS.

Audio wise, Raiders is EXTREMELY complex. Like the Star Wars trilogy it had three specific release mixes with variations and differences plus a fourth mix that was not used. The mono mix had unique bits and has never been officially released though you can hear bits of it on the 2003 bonus DVD and in the Raiders in Concert live symphony performances. The Dolby Stereo is roughly what was used on all pre-widescreen editions on VHS, Beta and LaserDisc in the 80's. The best iteration of that is the 1991 Japan LaserDisc reissue with PCM digital sound. This iteration is more of a home version as it doesn't really have much surround. Yet it retains dynamic range unlike the 1985 home video remix of Star Wars' Dolby Stereo track. The 70mm Dolby six track magnetic audio was supposedly used in making the excellent sounding 5.1 made for the DVD release. Before the release the film was mixed in the very short lived VistaSonic process which was Paramount backed. This was dropped very last minute as the system had tons of playback issues and the film was apparently hastily remixed in Dolby formats. When the first letterboxed transfer showed up on the 1992 Paramount LaserDisc release all of a sudden the Dolby Surround encoded matrix track it contained is without question the best sounding mix of Raiders you can find anywhere. It is more aggressive than the Dolby Stereo, more punchy than the DVD 5.1 and even contains a unique different sound effect which indicates it is clearly a different mix. It is unknown if this is the abandoned VistaSonic mix or a new quiet Dolby Surround home mix akin to the 1993 Star Wars Definitive Collection remix. To this day, the LaserDisc Dolby surround is the best sounding version of Raiders you are likely ever to hear. Even though it isn't discrete.
The Blu-ray remix though supervised by Ben Burtt went overboard on making everything aggressive and modernized. The LFE is virtually nonstop even in dialogue scenes. It is a textbook case of revisionist audio desecration. The 4K Blu-ray Atmos merely tames the LFE and reduces impact even more by moving around more elements and adding more processing. Both of these remixes are a crime.

2011/2025 WB Blu-ray for correct audio (2010 release has audio issue)

The Atmos is more processed and moves the sound around more so it is inferior to the older 5.1 iterations. On release Temple of Doom had 70mm, 35mm Dolby Stereo and mono mixes. The mono was for 16mm and other outlets and is presumably close to if not a mixdown of the stereo. It is seemingly the last Lucasfilm title that had a mono mix made. The Dolby Stereo is one of the most aggressive matrix mixes ever made and is still a blast to this day on the letterbox LaserDisc release. It is more aggressive than any of the 5.1 discrete versions which is either due to studios taming the audio later or the 35mm mix being handled a bit differently to the 70mm mix. In terms of releases today, the LaserDisc still sounds better than DVD, Blu-ray or 4K Blu-ray because of this factor.

The Paramount 4K Blu-ray has a much better new scan that removes the original extremely dated color grading. This is an improvement on one hand but a definite revisionist change on the other. There is the expected grain management and slight HDR issues in addition to encoding quirks from Paramount. It is a giant improvement over the original Blu-ray but the color change and other issues means that the Blu-ray is one to keep for purists to have the as-is original iteration of the film's presentation. Audio wise the film has been remixed into Atmos but it merely seems like a slightly tweaked and frankly tamed version of the original 5.1. Of the two I prefer the Blu-ray 5.1. The original Blu-ray was Dolby TrueHD and the reissue Blu-ray in the four film Blu-ray collection boxset was DTS-HDMA.

WB 4K Blu-ray only has Final Cut and contains a bad Atmos remix with new sound effects. Original Final Cut mix was removed.

Sony Global 4K Blu-ray > WB US 4K Blu-ray

Sony Blu-ray only has 5.1, not Atmos

Kino Lorber 4K Blu-ray disappointing review
