I was comparing to this impression of a 787 which is a 787-3

Now they look very similar, but clearly the pics of the production 787 show how different it really is.
Also your pictures clearly show it isn't 747-8 like either, and personaly I think it is more blended and swept than those on the 737, so there goes the theory that Phil and Nick had that the design was stolen from Boeing.
