What I do find interesting is the lack of evidence of clone brush use, and the fact that the pattern of white markings on the side of the neck appear identical, though rotated, on the remaining flesh.
The large white patch, the three patches below, and the line of tiny patches above appear in both pictures, only from a different angle.
I honestly cannot find any evidence of photochopping in this case.

I vote "probably real."
