There's less grain and more detail, yes, but the stuff in the back that was diffused by the smoke and haze now looks smudgy and blobby. Look at the storm trooper on the right, and the wall paneling next to him. I feel like I'm looking at plasticine.
If you don't see anything wrong with it, that's fine with me. It just irks me is all. Who knows, maybe when I see it in motion, it won't irk me as much. Besides, I've seen much, MUCH worse on other films on BD...
