It's not offline CG for sure, maybe offline rendered in the engine, can't tell it right now.
The skin shader is very nice, lighting too. Asset is scan based and well executed, although to me it feels like the eyelids are too thin.
It definitely lacks hair and fur rendering though, no peachfuzz and the eyelids are textured poly planes only. There may be some shadowing issues as well, bit harder to tell.
Another issue that's not as evident from this picture, but was noticeable in the trailers, is that the facial deformations are a bit off. The soft tissues around the mouth and cheek seem to gain extra volume here and there and the facial expressions aren't as nice too look at sometimes. I'd say that TLOU 2 is much better on this front, but I can't say if it is because, or depsite of, using hand crafted faces instead of scans...
