4K Blu-ray

Universal Blu-ray has a higher bitrate DTS-HD 5.1 track

Upscaled from the 2K DI. Caps are here. While not as dramatic an upgrade as Jackie Brown, color reproduction and especially the reveal of additional highlight information that were completely blown-out on the old master make this a great upgrade regardless. See Uma Thurman’s face in the above cap. Japan Cut: Japan DVD

Japan DVD has more extras compared to the HD/UHD releases

The Ultimate Matrix Collection DVD/Blu-ray has extras not on the 4K Blu-ray box set

Different colors compared to the DVD/2009 Blu-ray/Theatrical cut

The 4K Blu-ray and Blu-ray lack the bonus features found in the old Collector's Edition DVD release. The France Blu-ray has all extras plus an isolated score.

Neon 4K Blu-ray, Arrow 4K Blu-ray, Umbrella Blu-ray, and Korea Plain Archive Blu-ray all have differing extras

4K Blu-ray caveat: mostly great video but the 4K Blu-rays have had additional DNR applied in some scenes on top of the DNR that had been applied in post-production and was already present on the DVDs & Blu-rays

The 2020 Blu-ray may be better than the 4K Blu-ray?

New Line Blu-ray have the original 6.1 mixes

4K Blu-ray set is missing extras from the old Blu-ray/DVD releases

A scream in one scene is missing from both UHD tracks, see post

Italy Dynit Blu-ray has the best picture quality but has no English subtitles or original theatrical 6.1 mix.

All "4K Remastered" and 4K Blu-ray releases (including from Disney) are taken from a 35mm filmout rather than the original digital source, and then heavily DNR'd, destroying original detail and making lines smearier than before. The Japan Disney 4K Blu-ray is the least bad presentation of the 4K remaster, being encoded with a very healthy bitrate and HDR10+ metadata, and with a top-notch DTS:X remix, with the original 6.1 mix included on the pack-in "4K Remastered" Blu-ray.

The film has multiple English subtitle translations, and the Disney subtitles done by Linda Hoaglund and Judith Aley with Aura are often seen as the best translation, with these subtitles present on the Japan Disney 4K Blu-ray, making this the definitive option for viewers who want to watch the film in Japanese with English subtitles.

The DTS-HD 5.1 on the 4K Blu-ray. The Atmos is compressed. https://forum.blu-ray.com/showpost.php?p=22426684&postcount=840 

The Director's Cut DVD has some exclusive features like an isolated score track.

Better than the original 2019 4K Blu-ray, but there are a few shots with heavy DNR that look worse than the old 4K Blu-ray. The 2024 France StudioCanal 4K Blu-ray has a better encode than the 2024 Universal 4K Blu-ray (but forced France subs)
