Thanks for the answers. The 720p looks great so I was just asking out of personal curiosity. For films as old as 1977, we're reaching a point where anything above start to only provide further definition to the film grain itself, if that.
As far as the colors, I did see the disclaimer on the first page but I didn't know if that referred to the original despecialized edition or the version 2.0 since the color in that specific scene seems to vary between the two.
