I see you don't understand. Either it is or it is not lost. By lost I mean unrecoverable with any method because there is not enough information to recover from. In any photo some detail has been lost. This is trivially proven, as the amount of detail in the actual scene was many, many orders of magnitude more than in the photo file. Detail that has been lost cannot be recovered, it can only be replaced with something that makes contextual sense which is what AI is doing here.
