> International WB 4K Blu-ray see caps. While WB has better highlights, Criterion resolves grains better and is believed to have a more accurate color grading.

For Criterion 4K Blu-ray: The better resolution and the subtly adjusted grading paired with HDR makes for a more rounded, fine-tuned experience. The encoding is a leap forward from the Blu-ray as darker shots are no longer a macroblocking mess on the 4K.

Both the US Arrow 4K Blu-ray and UK Shameless 4K Blu-ray are better than the horrible grade of the France Le Chat Qui Fume which has blacks looking greenish and milky with some yellow push. However, comparing these two, there's significant tradeoffs; Arrow has less black crush and some shots seems to be better graded but it's worse in some shots with a slight magenta grade; the UK Shameless 4K Blu-ray has a better color grading.

(some may prefer Synapse's grading, while some prefer Shameless's grading)

In the Lionsgate US/UK 6-disc set, there are 4 discs of the main feature. For whatever reason, the 4K discs lack the *original track. The Germany 4K Blu-ray release is different on this matter.

1. UBD: Final Cut: Atmos, DD2.0

2. UBD: Redux/Theatrical: Atmos

3. BD: Final Cut: Atmos, DD2.0

4. BD: Redux/Theatrical: Dtru5.1 (Redux mix?), DD5.1 (?), DD5.1 (Theatrical only), DD2.0 (downmix??)

   1. As a result the Theatrical Cut has 4 tracks, The Redux has 3. Differences are unclear.

5. BD: Hearts of Darkness

6. BD: Special Features

4K Blu-ray is denoised

The 2025 SteelBook uses the same transfer as the 2014 Japan Studio Ghibli Blu-ray and 2015 Discotek US Blu-ray but with better white balance.

UK Arrow Blu-ray and Germany Koch Media Blu-ray have exclusive extras

Included in the Complete Kubrick box set with FiM encode of the same master from the WB release without the filtering, 1.85 ratio restored for US Cut; both US and International Cuts are 4K.

No Blu-ray or DVD release until the Criterion 4K Blu-ray has presented the US in its original theatrical aspect ratio of 1.85:1. The International Cut has never been presented in it's OAR of 1.66:1 in any home video releases.

The packaging on the back of the WB 4K Blu-ray incorrectly states it as 1.85:1 when the movie is actually 1.78:1 as is the original Blu-ray. 

The DV/HDR grade is tasteful and not overdone. SC has better compression, though not flawless; encoded by FiM, but Criterion also holds up quite well. Both releases claim to be approved by Lynch.

SC has a missing fade that Criterion reinstated.

The film was originally mixed in Dolby Stereo (matrixed LCRS). For the 4K restoration, this mix has been transferred from the original magnetic elements and remastered with Lynch's supervision. Unfortunately, the fidelity suffered in the process, with many sections ending up significantly less detailed due to a noise reduction pass. This track has been altered compared to the original, with reverb added to some dialogue, different ambient sound effects, changed panning, and extended bass.

For the unrestored mix, there are two major options, each with its own merits and flaws. The 2001 Paramount DVD, which I would say is the best well-rounded mastering, and the 1999 Japanese LaserDisc, which has noticeably better clarity and high-end detail, as well as better dynamics, but suffers from occasional distortion and has less bass than the DVD.

The LD also has some ambiance buried too low in the mix, and some dialogue panned more to the centre than the DVD. There are no content changes I was able to find. Unfortunately, I don't know what accounts for those differences.

The other available tracks all have more significant flaws. The Italian and Japanese BDs use the same base mastering as the DVD, but with some patching in a few shots. HD-DVD is sourced from an inferior transfer, the same as the Momentum DVD.

The 5.1 remix, originally introduced on the 2002 DVD, and carried over without changes to the 2009 BD is a light and mostly faithful remix, with fairly minimal LFE and surround use, but still potentially worthwhile as the only discrete track.

> StudioCanal UK for the inclusion of original mono, more extras

Though note its different color grading from the IP-sourced but poorly compressed Fun City Editions US Blu-ray (caps)

Judging from spectrograms at https://forum.blu-ray.com/showpost.php?p=23933756&postcount=57, Fun City Editions US Blu-ray appears to have marginally less filtering than Radiance 4K Blu-ray (whose padded 16-bit depth is a non-issue). There are also loudness differences, though it's unclear whether dynamic range also differs. Caveat: need to A/B both tracks to confirm, but no one has posted actual A/B impressions.

Identical. Arrow 4K Blu-ray is lossy transcode.

However it seems like the Britain Fox Blu-ray is slightly cropped see caps

US Arbelos Blu-ray (encoded by FiM) or UK MoC Blu-ray. Both are the same 4K restoration. No comparison available
