The picture Jo21 is of the same character model I posted. The blurry collar texture that he points out is visible in the second picture I posted, as is the aliasing on the hair. Difference is, his picture is direct feed, rather than a magazine scan, so it's easier to see these imperfections.
Compare:

The one of the girl I posted is also on IGN, also direct feed. It's imperfections are again easier to see:

So, it's seeming more and more likely that those are the in game cut scenes graphics after all.
