One thing I noticed was that there was pretty much no visible grain in the film, even in the optical shots (well, I mean there was a tiny bit, but quite insignificant). This contrasted what I have seen of the GOUT. I don't own ROTJ GOUT, so I don't know if the opticals are as grainy as SW and ESB. But the lightsaber scenes were pretty much 100% identical in quality to the surrounding ones. Obviously a positive release print and the fact that the focus fluxuated a bit would have influenced this, but I could still see some light grain and there were never any jumpy moments (that extra-contrasty shot of Luke reacting to Vader's amputation being an exception).

That makes sense to me. ROTJ has never been a really grainy film. I just took a peek at my GOUT disc for the first time in years and it reflects this but the print used has dirt and speckles crop up more than I noticed originally. Not to mention the lovely frame border on the left side that keeps popping up. On the GOUT it looks more like analog noise than film grain.
