I just watched the PSB clip alongside Adywans' theatrical reconstruction at the same time in two seperate video players on my monitor. The differences are pretty incredible in the snow and ice scenes. I had thought that the 2004 dvd was extremely blue, and when I saw Adywan's color corrected scenes those looked "right" to me, but now I have to go back and revise my opinion.
The blues in the PSB scenes are just the right kind of pastel hues that look otherworldly, and almost a little dreamlike. It definitely changes the tone of the planet. I think the ability for Ady or anyone else to go back and re-re-color correct ESB alone makes this project worth the effort.
Man, I wish I had a projector or otherwise big screen to watch this or PG on.
