Does anybody know what post-processing is applied to ProRaw images from iOS? I'm guessing true raw (Halide, etc) have none at all, but I recall reading the ProRaw had some applied. I just haven't seen a summary of which steps are applied.

90% of the time, my iPhone photos are fine straight out of the camera as HEIC. But every once in a while, I get something like is described here (or in several other recent similar articles).

They are already demosaiced (this I know for sure and is easy to verify). I also believe that they are the result of stacking several photos to increase the dynamic range and reduce noise (see [0][1]).

Even for the "true raw" ones, I don't know if they're truly raw. Do they have distortion and light fall-off correction applied?
