Well, typically the raw ADC readout data already gets processed in camera (°), before it gets stored in the RAW file.
(°): noise reduction ("star eater" if overdone), dead pixel elimination, PDAF pixel interpolation, sharpening, etc.pp.
Not to mention advanced camera techniques, say Hires, HDR, ND, and of course all other multi-exposure modes that always get even more pre-cooked before the data gets written to the presumatly "raw" file.
So how would you rate SOOC JPEG files?
They're already demosaiced, white balanced, and whatnot.
Polaroid: always processed.
