Germany DTS-HD 6.1 is inferior due to clipping.

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.
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 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.

(unsure about Criterion, which lacks the 5.1 on the Arrow)
