It isn't even a close call. The WoP screenshot looks like garbage. The CoD shot looks like the photo. WoP may have more trees, but that doesn't make it look more like the landscape in the photo.
Seriously, it is not possible to look at those 3 shots and not say that WoP looks more real unless you are on the graphic arts staff for WoP, and even they would probably admit that CoD looks better.
