I haven’t seen the 4K cut of 2020 SE. I was doing a run through of the films on laserdisc I couldn’t be bothered to finish 1997 0r 2000 sets. I did watch a bit of the 2004 Empire Pal DVD but it’s not fresh in my mind. I did watch some of 97 35mm of Empire, scratches and some wobble a bit of dirt. Nice color though much nicer than anything on home video.
I think my favorite is probably somewhere between 70mm Empire premiere cut and 35mm 4k80. Harmy is good for a super clean modern edit of the original. An approximation.
