Being pragmatic, the after is a good restoration. There is nothing really lost (except some sharpness that could be put back). The main failing of AI is on faces because our brains are so hardwired to see any changes or weirdness. This is the sort of image that is perfect for AI because the subject's face is already occluded.
This is the first image I tried:
https://i.imgur.com/MXgthty.jpeg (before)
https://i.imgur.com/Y5lGcnx.png (after)
Sure, I could manually correct that quite easily and would do a better job, but that image is not important to us, it would just be nicer to have it than not.
I'll probably wait for the next version of this model before committing to doing it, but its exciting that we're almost there.
