Honestly, no and that's why it's so aggravating. I originally bought it pre-ProRAW because I wanted RAW ability and occasionally for the manual control ability, but for the price? No.
This seems like such an easy and logical fix and I'm sure there's some kind of reasoning behind why Apple did it. But, (to me) this seems like Apple decided that a majority of people don't know how to properly use the 3x camera therefore this is how they'll do it. As for the rest of the processing? Again, I think it's Apple assuming that a vast majority of the time, people will be viewing these photos on screen and in social media apps and most won't be zooming in at any great detail to see the smudgy mess they actually are.
I agree, I think Apple massively underestimated how closely people will be inspecting photos from the new devices.
Just pray it’s sorted in software if not, there’ll be a lot of skeptics about come the next iPhone launch.
