I don’t think a collage is the right way to describe it, because it implies that it’s literally parts of the training data copied together which a lot of people think but it’s a lot more indirect than that, but I agree that it’s not a photo because a photo is of a real thing It’s more like the training data is used to score the generated images against to guide it into producing something that looks similar to a real image
