I do photography and art work, just for fun, not professionally. So perhaps I notice shades of grey more than some people. But I definitely notice blotchy shadows, especially around text. I attached a screenshot taken from that last video review. The actual screenshot is on the left and another view of it is on the right wherein I turned up the contrast in Photoshop to make the shadows easier to see. Admittedly this is subtle for some people's eyes, if they see it at all. But for my eyes it glares back at me and becomes a distraction. Look at the shadow around the chapter title. That is pretty obviously a shadow.

EDIT: I've seen these blotches/shadows in every review video. At least I'm not seeing blues in this one. I do think the shadows are slightly less evident than in th 3 PW1s I tried. Those were all very blue too. So the PW2 is an improvement, but not enough for my eyes.
