I always thought that the THX Remastered versions of the trilogy had a visual pass done to clean up the garbage mattes and some of the blue/green screen borders. I remember seeing some kind of behind the scenes video that showed how they had just cleaned up a lot of those effects for that release. But in doing research now I’m finding that they were just essentially a copy of the 1993 Laserdiscs. So maybe the clean up pass was done then? Or am I experiencing some kind of Mandela Effect?
