I’m interested in why you seem to prefer the 2011 BluRays as a source over the 19SE. They have their pros and cons, and the former has a long history of being reviled.
Perhaps even though the unmodified 19SE is more palatable than the 2011, modified versions of each could shake that up?
In the case of ROTJ, I found the 19SE and 4K83 to cohere pretty well, far moreso than the 2011.
