While the current revision had been improved a bit, I've seen the previous case in person at Gamescom. And boy, you do see these marks in normal lighting situations. Check the
Gamescom thread for some photos that were taken by community members. Though there's the caveat that at least my photos aren't the sharpest and changing lighting in motion makes them more apparent than still images.
If my Pandora is any indication, black paint on black case is not much of an issue. And that wasn't quite the high quality paint job to be honest.
