I have yet to see more than a few pieces of the LPP version, but holy crappe, that Technicolor preview looks amazing. If the whole movie was available in that quality, I would watch the hell out of that!
Very interesting to see how closely it matches the colors of Despecialized 2.5, as well. The inconsistencies from shot to shot are in exactly the same places: sometimes the Death Star interior is blue-green, sometimes straight-up blue, sometimes a bit purple-ish, sometimes even light grey. Every time it changes it’s in exactly the same way as Harmy’s version, and it looks a bit green-tinted more often than not. Clearly that is just the way those prints looked—I think it would be doing them a disservice to ‘correct’ those inconsistencies or biases out of it. So what if it’s a bit green? I think it flatters the overall cinematography quite nicely.
I really like seeing the grain levels go up on the opticals, also: it reminds me I’m looking at the real thing and not an overly-scrubbed version.
