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. As for the change in color, I think it looks better at times but I’m by no means “impressed” and no I’m not horrified by the bluray, other than Luke’s green lightsaber on the DVD of ANH.
