Did the blu-ray actually try to fix the colors from 2004? Besides the minor lightsaber fixes, did they try to make Hoth less blue or colors not quite as oversaturated?
Yes. Only the Hoth blue, though.
I wasn’t aware that they’d changed that between 04 and 11. But yeah, the films in general have the exact same color timing as in 2004.
I haven’t actually bothered to check, this is just what I’ve heard.
