Consider that a 4K camera only has 2k4k pixels whereas a 4K screen has 2k4k*3 subpixels. 2/3 of the image is just dreamed up by the ISP (image signal processor) when it debayers the raw image. I'm not aware of any consumer hardware that has open source ISP firmware or claims to optimize for accuracy over beauty.

Okay, but a camera doing this is unlikely to dream up plausible features that didn't actually exist in the scene.

Of course it is! Try feeding static into a modern ISP. It will find patterns that don't exist.
