your brain does lots of preprocessing to create a stable view of "reality", glossing over blind spots, retinal blood flow, etc. in a way we are always hallucinating, and it seems natural that computers should learn what we are actually paying attention to in video, and focus on that

Yes! E.g. AAA games render the entire 4k screen with the highest graphics, but only a small spot hits the part of retina that can perceive jagged edges or lighting details.
