I was listened to an episode of the Film Formally podcast where they had Drew Stewart on to talk about all the various changes made to Star Wars.

Drew mentioned that when the 97 SE version was created, Lucasfilm did a 1080p scan of the original negative. The scan was then digitally cleaned up, revised with new cgi effects and deleted scenes, and then printed back onto film for a new “original negative.”

For the 4K release, did they just take the 97 SE and upscale it to 4K, as well as upscaling all the other scenes that have been altered since (Hayden in ROTJ, new versions of Jabba, Ian McDiarmid in empire)? Wouldn’t that mean it’s not a true 4K restoration since the only film print that exists in lucasfilm’s archives is the 97 SE, which is locked at 1080p?

Sorry in advance if this has already been addressed.
