Wouldn't help much for a "camera review". The raw would just be a black-and-white mosaic that would look awful. What you want is the processed jpeg out of the iPhone along with the edited ProRAW. I'm not sure if the iPhone can do this but a lot of cameras can shoot in RAW+JPEG mode.
Traditional RAW* wouldn’t be a black-and-white mosaic. It just would be data. RAW’s need to be demosaiced to be seen visually, which makes it dependent on software (or algorithm).
