What is thematic photography?

I wonder if there is a scientific definition?

I can only vividly say that thematic photography is a kind of "propositional composition".

Clothing, props, lighting and background are all decided according to a specific theme. . . . . To complete a photo effect that conforms to the proposition.

Of course, most studios take photos first or have a general idea before, and then give it a proper name after the photos come out. Like many photographic creations, there are photos before names.
