This sounds like an awesome project! Are you going (Han) solo on this, Willarob, or are others helping?
I am impressed by the screenshot comparison from up above. The blu-ray does SEEM sharper but it could just be artificial sharpening.
Also, take a look at 3pO’s exposed stomach area. Much more detail in the 4k than the bluray.
Dr. Dre is helping with the colors, but I’m running solo on the cleanup at the moment, mainly because of the staggering amount of data involved. Even if I was to copy all of the data for a single reel onto Hard Disks and ship them out, you need a beast of a machine to process it, or it really is a case of click, wait 10 seconds, click, and believe me - that gets old real fast. A basic cleanup on a single frame typically takes between 1 and 5 minutes depending on how thorough, but on a slower PC it can take nearly an hour. Which is why I abandoned the 4k idea quickly the last time I tried it.
