the camera is dumb & can never resolve anywhere near the human eye, even mastering the M mode cannot achieve that. why showcase equipment imperfection/limitation when you have tools at your disposal to at least process closer to something as you see it?
PP does not necessarily equate to fakeness, I'd see it as patching up the limitations of technology, and then more if necessary for artistic requirements.
PP is also a skill no less than operating the camera proficiently.
Getting a PnS and PP all the way also cannot work, a PnS jpeg file cannot tolerate manipulation. and it's internal PP is not what you want all the time. since no technology can read your mind, it's necessary to use a dslr and maximize it's greater output workability.
