I think the Japan Special Collection for Star Wars has the 1985 digital remix not the 77 35mm mix. Jedi is missing the Huttese subtitles for Jabba, i’m sure there are other things people will notice i did not.

You also have the picture shifted up to fit the Japanese subtitles below the letterboxing.

The picture is not as good as the THX remaster but it doesn’t have the problems caused by the early dnr method they used in the 90s to reduce grain.

The colors i would say are not to be relied upon. Telecines were almost never accurate.

fans prized this release for the ability to stop on a frame in full featured CAV mode, it also was the first widescreen transfer. Letterboxed tranfers paired with digital audio. In America we got Pan and Scan releases of Star Wars and Empire with no digital option until much later. Widescreen versions only started to be released in North America in 1989.
