Here’s something interesting:

http://screenshotcomparison.com/comparison/156826/picture:1The new logos are definitely 100% accurate to ROTJ, since they come from a 1983 35mm print and yet, the v1.0 logos, taken from GOUT, have very different spacing and fonts.
Whoah. Well there was always the theory that the GOUT 77 crawl was a reconstruction rather than the real thing… I wonder if it could apply to other things as well – or if someone was lazy and just re-used the same Lucasfilm logo (and ALTA) scan three times, and it is “theatrical”, just for a different film.
