Was it ever determined if the Technidisc pressed ESB and ROTJ were similar to the SW transfer?

About ESB, I know that the Special Collection (Japan) and SWE (Pioneer USA) is two different transfers of the same master, a master which is unfortunately very problematic in its colors and its many missing frames around reel changes and also in between them, my SWE copy (Pioneer USA) lacks more than hundred frames in total and I think the Special Collection is even worse. How the pressings of Pioneer Japan, Mitsubishi and Technidisc compare, especially in the colors is something I'm curious about. I have asked Aluminum Falcon to check his Mitsubishi copy for me and Darth Mallwalker said he would check his copies.

Some examples of the ugly hues in my Pioneer copy compared to the more natural hues seen in the '85 LD:

Pretty nasty hues... the '85 release isn't perfect either, it's often too yellow and green, but overall the original timing is pretty much there. The Special Collection and SWE release of Star Wars is also plagued by these unnatural hues in places, that's one of the reasons why the Technidisc pressing of the first film was so great and it didn't lack any frames, unfortunately it seems the other pressings of ESB are made from the same master but I have a tiny, tiny hope that they could have at least more stable colors.
