But people in front of blue screens normally appear as themselves in front of a background. That would mean the image itself has been digitally altered, right? Or that it is real.

As Koy said, yes, not directly a blue screen. A green sock, or blue sock, or whatever color was appropriate based on the (other) stuff. Of course it is 'digitally altered', every single piece of film you see nowadays is (in some way) digitally processed. Heck, they've been doing it for half a century (remember the old driving in a car in front of a moving background stuff? Same thing, just lower quality). This sort of thing is pretty common, and trivial to do (you just have it coated in one color, and then tell the software to remove all pixels of X color, with some more complexity but not much).
