Past Lucasfilm releases have always been an exercise in how to get the most money from the least amount of effort. In the extremely unlikely scenario Lucasfilm issues a new improved OOT home video release, er, ever, it’s going to have the 81 crawl, the 93 audio, effed up colors, and degrain/regrain, at the very least–and likely some horrifying audio remastering as well, because that’s the established workflow and changing that would require effort. Access to the original negative only matters if you care about the film.
Even THAT would be something.
