Towne32 is right. The upscaling is just for the deleted scenes. They will never look as good as the rest of the film no matter what we could possibly do, but they blend in better than the flat upscale I had used before.
And I’m probably going to use the BluRay for Episode III, since to my eyes it looks pretty good and won’t have any encoding mistakes that I might not spot from schorman’s V1. Episode II on the other hand looks waaaaay better than the BluRay, so I’ll use schorman no matter what mistakes might be there. Episode I was the BluRay color corrected similarly to KK650 (though not as far), and with added grain to counter the overuse of DVNR.
