Some of the confetti effects are out of sync with the Bluray during the Coruscant portion of the SE Victory Celebration. There’s no clear signs that they redid the Temple and Senate, though, which was what I was looking for. Also, the horrendous Bluray red glow over Vader’s funeral pyre (and the subsequent reddening of the bottom half of the sky) are gone.

EDIT:
I can’t believe they made the compositing of Hayden worse. And why is he wall-eyed? It’s the same in the Bluray but surely his eyes aren’t actually doing that in the original footage they used; it must be edited. I think his left eye (closest to Obi Wan) is legit and the right eye must be ‘adjusted’ so he looks more forwards. Cover up the (his) right side of his face and it looks like he’s looking at someone stood in front of Ben.
