The GOUT crawl has a different color balance than the EoD clip; the color on the EoD clip seems more "correct," but I'm assuming that the GOUT version was timed to match the 1993 transfer. Also, the GOUT seems to be sharper (the SW logo doesn't lose as much detail when it gets really small), and have more info on the edges (this was discussed way back in 2006 during the whole flap over the clip in the GOUT trailer, which turned out to be a digitally manipulated version of the crawl, where the SW logo was a lot closer when the text started scrolling up).

I can't compare the flyover, because in EoD they just used the 2004 version and painted over (most of) the desaturated/white lasers. So we get the Star Destroyer shooting thin green lines instead of thin white lines. No idea why they didn't use the original version...

Not sure if it's the same source as EoD but a different transfer. If the source of the GOUT crawl were properly transferred and mastered, it would probably look a lot better than it does now.

The EoD, the GOUT crawl, and the (non-SE) images in Rinzler's book seem to point to the existence of a high-quality source, possibly a separate one from George's personal Technicolor print. Of course, as long as Lucas and co. refuse to rationally and honestly discuss anything relating to the original versions, we can only guess...
