You know, I’ve always wondered about that section in the middle of the ROTJ blu ray where everything goes soft. Do we know what the reason is for that? Releasing a transfer that’s literally out of focus seems too careless even for Lucasfilm.
There are a few points before wipes that go soft and the color shifts. I assumed it’s due to using something downstream of the o neg for a few wipes. The one that comes to mind mainly is wicket and Leia, with a wipe to the death star. Perhaps they didn’t have all the original elements for the latter?
