In my opinion, this makes little sense. The image processing of any digitally taken picture involves so many corrections that these wouldn't pass such a test of "photograph" either. These either happen by choice of the photographer when developing raw images with tools like darktable, Adobe Lightroom, ... because they want to achieve a certain look - or automatically without interaction in your smartphone/DSLR if one is only interested in getting any picture or video out of the other end (remember how iPhones botched the colored sky during the California wildfires because that's something that wasn't foreseen?). Even chemically developing images taken on photographic film gives freedom with the results.
