This seems to be a rendering efficiency innovation, not particular to scanning. That means it applies to artificially generated environments, whether photo realistic or stylized, and whether based on a real environment or a completely fictional one. But of course, any photorealistic, extremely faithful to the smallest detail, rendering of a real place is going to involve a lot of scanning. That is true for any kind of rendering.
