So, have only some of the ‘04/‘11 changes been redone but others pulled from the same source? Off the top of my head, so far we’ve spotted the aurebesh tractor beam readout on the Death Star in ANH and Anakin’s eyebrows in RotJ as having been redone.
What about the blinking Ewoks? R2 spazzing out during the Endor battle? The first shot in the approach to Mos Eisley (which now has ‘97 and ‘04 changes)?
