Most of the reason people appreciate the new transfers is because of the color grading. Sure it’s dull, but when I turn up the color on my TV it looks great. It doesn’t have as many unfixable issues when it comes to grading as the 2011, like the crushed blacks. There’s more detail and the original colors are still there and can be restored, where as with the 2011 ones, if you desaturate it it just looks duller. The colors are just completely off. You basically have to redo the entire color map.
Adywan’s color grades are better then any of the official releases, but that’s because he’s an expert colorist. He actually did redo the entire color map. But if I’m just picking a version of the movie that I can easily pull up, and I’m choosing between the ugly ass over-saturated 2011 Blu-Rays and pulling up Disney+ and turning the color on my TV up, I’m choosing the latter.
The 2020 ones may have more issues, but you aren’t gonna notice them as much as a blatant ugly color grade.
But there are shots that look godawful from the 2020 Blu-Rays, like that one in the Millennium Falcon. I noticed it in my last rewatch and wondered what the fuck happened.
