I’d really love to see what amount of detail you could get from the speeder shot. You could always add grain to it afterwards to make it appear more natural. Since cleaning up the shot at all is already revisionism in itself, I’d say it’s fair to cheat a bit like that.
Also to clean up the non-Blu-ray parts of that Despecialized shot, I used AviSynth (and some manual painting in AfterEffects), which quite likely might have produced inferior results to what your new tool might do.
Furthermore we now have much better sources for that shot available (like 4K77).
