are they regular DNG files, or linear DNG files? I remember Apple explicitly mentioning linear DNG, which means they at least have demosaicked the image, probably a lot more
You are right that they are demosaiced raw files but that’s about it
> Instead, ProRAW stores results of computational photography right inside the RAW. This is another reason they need to store demosaiced data, as these algorithms operate on color, not RAW data. Once you demosaic, there’s no going back. I mean, what would you even call that, remosaic?
> Smart HDR does this in the least destructive way. Apple worked with Adobe to introduce a new type of tag into the DNG standard, called a “Profile Gain Table Map.” This data gives your editor everything it needs to know to tone map your photo image and end up with results identical to the first party camera. Because it’s separate data, you can turn down its strength, or turn it off completely.
