I agree.
As a former photographer, I’m guessing it was taken with a wide angle lens which distorts the size of objects in the front to appear larger, and shrinks objects in the background.
I’ve been able to take a picture with two objects only 2 feet apart, but appear 1/3 the size depending on the lens used.
Not much to see IMHO...and I don’t think you could PS something like that without leaving artifacts / false shadows just right.
Occams Razor: the simplest answer is probably right.
