Thanks for the info, TServo! Hadn't noticed that the transition from '81 crawl to '77 flyover was a dissolve as well. There is panning in it alright, see the wipe to the Jawa canyon for one example but just like you said it's not as frequent as in other pan & scan transfers.
Home Video:
'82 - '92: No "burn" marks, cloudy x-wing take off composite
'92 - '95: "Burn" marks, cloudless x-wing take off composite
However all theatrical sources that has surfaced so far, does have the "burn" marks, cloudless composite or not.
I think it's quite sloppy that they didn't rectify this issue after the first batch of prints went out...
