I was too young to see any movie in 1977, let alone SW but I remember going to see ANH during the 1997 re-release and thinking how strange the print looked (besides all the CG). It was distracting to the point where I wasn’t sure I enjoyed the experience. I think those issues partially carried over to the SE blu-rays.
Similar experience for me. I grew up with the original on home video and saw the Special Editions in theaters, but the most remarkable thing about 4K77 is that it looks like a film shot in the ‘70s and I’ve literally never seen it look like this before. Even if Disney/Lucasfilm were eventually to release the original cuts on home video, I doubt they’d look like this just because it’s so radically different from how the films have been presented for the past three decades.
