Wow that is weird.
That "original" frame simply doesn't exist in the DVD version that I have. Notice how Jabba's eyes are slightly more open on the original, and the appearance of a "hole" on his chin that is absent on the original. At no point in the shot does this hole disappear on the DVD, so I assume that this effect was redone for the DVD along with the the rest of the digital additions in this sequence, or the end of this shot was perhaps cut off.
If the character was redone, global color correction wouldn't really work, as the colors of the separate elements may be different.
Sorry if this has been said before, I just noticed it.
