If you watch the comparisons in Harmy’s Sources Documentary or Mike Verta’s Legacy videos and aren’t impressed by the change in color and horrified by the bluray colors, you’ve go to have eye problems.
The blu ray looks a bit worse in Harmy’s Sources Documentary than it actually does because it’s a compressed Youtube video.
But the re-graded colors in that clip suffer from the same problems, so the comparison is still valid.
And Leia was noticeably purple on my DVDs, so I’m sure that carried over to the bluray, even if it’s boosted by compression in the youtube clip.
The color re-grade shown in the clip is way to yellow, but like some of us have said, 2.7 looks great.
