It’s not enough to call it just an image model though. Not quite video either because it’s so specific to rendering images of the world.

Thus, “world model”?

The problem I have with “world” is it should imply so much more depth. To me this is actually a “POV image model” or “First-person perspective model” (maybe we call this an FPM).

There could also be TPMs (third-person models).

This maps better to modern game and 3D dev phrasing, where “world model” might imply 3D object collections spatially organized in a cohesive file format - complete with interactivity, audio, and all the baseline constituents of what one might call a “world”.

FPMs and TPMs, think about it. Reserve POVMs for photographic realism.
