I am not just going by what I have seen in photos/videos, but going by reviews by the big sites and other users opinions on XDA etc. the majority of them say the same about viewing angles and blacks.
Perhaps the display is just very variable? Like the nexus 4, some say the viewing angles are awful and the display is washed out, however, others say that they are one X good (and from the one that I seen, I would also agree with regards to the viewing angles)
As for the pictures of the youtube video, no idea. Unfortunately a lot of the other videos showing viewing angles are pointless as they have bright stage/office lights shining on them with reflections all over the screen.
