Sure. I'm not saying it will represent reality 100%, but it could be good enough that you probably couldn't tell the difference. Current neural nets might perhaps not be able to upscale with no limit and still make it look good, but it's not like it can't be done. A good human artist could take a small grainy image and given enough effort draw an upscaled version that would be a very reasonable representation of what a larger image would have looked like, there's no reason to believe that artificial neural networks can't do the same.
