I know what you mean of the camera's PS, What I mean the PS is the "Afterward 后期" PS.
You have indicated that the camera’s PS. My opinion is it is not a PS. it is the parameter that is designed for the all mechanical part of the camera, such as shutter, aperture, which are depends of the camera man's photo taken experience of setting the proper Speed and Light for the best result. So the original picture done with out PS is the best one to tell, the cameraman’s skill and experience, this is my opinion, PS is just a software manipulating the Bits and Bytes of the in the 1 and 0 format. It is not a photo taking skill.
