The unique information would be the actual values read from the mosaic. There are common algorithms that assume correlations between color channels which is a rather perilous assumption, I’d think, in many cases, particularly where there is fine color differences that need to be preserved.

Yes. After demosacing, all the pixels are equal in the eyes of further processing. However, with a nod to George Orwell, some of the pixels, the ones that haven't been interpolated or otherwise guessed at, should be "more equal" than the others, and carry more weight in subsequent resampling.

Or maybe not. I'm just speculating here.
