I feel like R2 in that image (your Blu screenshot too) has some pretty weird unnatural stuff going on. I think your DE looks better because it's the same image, but blurred (due to downscale and compression). Blur can be a good thing when there's detail you DON'T want to see.

But really, forget it. That was one specific example and maybe it wasn't a good one. Most of my concern over the Blu Ray is just a vague uneasiness based on how long it took to figure out what exactly got changed in the DVD releases, not on any actual particular thing. I'm not worried at all about the things I can point out, I'm worried about the things I don't know about yet.
