I have not watched the whole thing, but I will share what I've found so far. Also, please know I am not comparing these to anything but memory and with other scenes within the workprint. Also, frame numbers and times aren't beginning frames of shots or scenes, I'm using VLC on a Mac and if there's a way to advance or reverse frame by frame, I don't know about it. With those disclaimers out of the way, here I go.

Frames 21729 through approx 22100, the lower left corner of the screen looks more teal than the rest of the shot on my monitor.

22527 (00:15:38:14) The sky on the horizon as seen through the cockpit, flashes wildly. This could be in all ESB versions, I don't have others immediately on hand.

31050 (~00:21:33:19) There is something very "right" about this shot. I wondered if it was 35mm? However, Luke's flight suit seems pale/washed out. I may just be used to the 2004 and newer vivid oranges?

~33921 (00:23:33:08) Display screen "grid" moves/flashes, and instead of looking like little squares displaying video, it looks like more like one big screen with dots all over it. They appear to crawl and move, and it gets worse the next time we see it, around frame 34110.

34368 All the flight suits are washed-out similar to Luke's in the scene listed above, kind of dull. Leia's hair is lighter brown, almost like red hair here, too.

46590 Luke's Flight suit is VERY bright here, almost fluorescent Yellow-orange

48357 (00:33:34:20) Smoke on the left side looks bright blue. Possibly intentional, possibly a blu-ray/DVD holdover?

51985 (00:36:06:00) The "glow" around hoth looks really bright, almost fluorescent blue. Is this correct? It looks too light and too bright on my screen.

52808 (00:36:40:07) EXCELLENT! The Star Destroyer lights on the left look like natural light photographed in '79… Also, I just love the colors of the ships during this whole sequence. Excellent blue TIE Fighters, etc. Nice work!

53057 (00:36:50:16) This cockpit shot is so beautiful! Is that 35mm? The colors are super warm and saturated.

55572 (00:38:35:11) Color palette seems to have gone Sepia here, more monochrome, definitely more brown- same with 55729 (00:38:42:00)

Color is awesome again at 55786 (00:38:44:09)

… And that's where I've left off. These were things that jumped out at me, they might all be absolutely correct and I'm just not used to seeing them.

In any case, it's looking great overall. I haven't gotten far enough into the movie to get to the audio sync issue, obviously, but everything I've seen feels more like Empire than it has in years. Thank you for that!
