The blue splotches are data loss. I'll have to patch them. They are in the Bluray and the DVD, but not in the 97 SE or the GOUT Lowry again. I really don't know what was wrong with them. They seem incapable of realigning faded color channels. It isn't that hard if you have a reference and for ANH we have the technicolor prints, an outstanding reference. They claim to have gone by that, but I don't think they shared it with Lowry and they then were working under a handicap. I've found that the red and blue channels are nicely in line, but the green one is all over the place. I can't even fully correct for how off it is, I can only get close and use other tools to make it look good. The magenta tone to the explosions and the blue artifacts in the dark areas, not to mention the lobster skintones, are all the result of the green channel being misaligned. There are may ways to correct for it, but unless you can track down what the core problem is, there will always be something wrong. Blown out whites and crushed blacks just make it harder to fix. Add to Lowry's mistakes the color grading choices by Lucasfilm and you get a really messed up movie.
