Nope. The image data _is_ actually lost. What happens is that it gets pimped with what on average was lost when a training process artificially degraded a train

Nope. The image data _is_ actually lost. What happens is that it gets pimped with what on average was lost when a training process artificially degraded a training set. For the results to look(sic) natural, you need both the training set and the degradation to be close to what you're shooting. If that is not the case, hallucination happens.
