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.
