The colors on the last shots of your LPP remind me of my '89 French Laserdisc:

Maybe because the print is slightly faded.
I wouldn't be surprised if the LPP print came off of the same source element as the '89 French LD transfer. From what I understand, this LPP was a Spanish (Latin American dub) mono print. It has the 1977 flyover composite at the start instead of the 1981 recomposite, and the image density/contrast change after the flyover suggests it came from a different element than the rest of the print (though from what I also understand, there was no physical splice on the print itself, meaning the join would have been made at a previous generation?)
Judging by the various foreign video releases prior to the THX remasters, the foreign-language crawls were never redone with "Episode IV" (on film), so I am assuming that any 1980s prints with foreign crawls would still have had that language's 1977 crawl element spliced on, complete with the old flyover. The LPP print had a faded, Dolby Stereo English crawl spliced on at the head, and my personal theory is that the LPP originally had the "La Guerra De Las Galaxias" title and Spanish crawl.
As for the rest of the print, while it's LPP and not faded itself, it seems to come from a source element that had mild color fading issues reminiscent of the '89 French LD, and the composites that were redone during the original run (the temple establishing shot, the X-Wing takeoff) match up with the '89 LD as well, so I wouldn't be surprised if the LPP was indeed sourced from the same, slightly fading element (with Spanish crawl+'77 flyover spliced on at the internegative stage?).
And actually, I also wonder if the same element, with some additional video color balance correction, wasn't also the source for the Technidisc LD, and then the Definitive Collection/GOUT masters...
