Perceptual hashes are just integer/byte encodings of images that were scaled down and had some transformations applied to them.

If you convert a hash into an array of pixels and reverse the transformations, you'll get some of the original image that was scaled down and hashed.

And if you then apply DLSS, you may even get the original image.
