Harmy,
I just finished watching the work print and while I haven't had a chance to do a detailed comparison at the GOUT, I did notice one issue that popped up towards the end....Vader's top button.
While they are the proper color for most of the council meeting, at 36:58 the top button switches back to blue. I checked the GOUT and it should be green in that shot. Strangely enough, two shots later, when the button becomes visible again (about 37:02), the color is blue in the GOUT.
In truth, I could care less about this minor issue, as the work print is simply marvelous. I only point it out because I understand that you wanted to be made aware of inconsistencies compared to the GOUT.
