Don't know if you're still updating this but I noticed a couple of undocumented changes in the first film when I IVTC'ed a LD-transfer recently, a couple of reframings akin to the Falcon zooms in ESB but usually a bit more subtle. This was often done when they went back to the negative (wipes, dissolves and flipped shots etc.). Examples of this can be seen in the remade detention shootout whenever they tinkered with the background:
Sometimes shots received a tighter framing and sometimes they were adjusted horizontally... I can post a few examples when I get access to it.
