Also the image you did share of the leaves shows the exact problem that I, and I am quite sure, others are having with the iPhone 13 Pro cameras. You can claim loss of quality all you want, but the only loss occurring that you can clearly see are the little blocky pixels. That weird texture on the leaves that looks watercolor-like is what I am talking about.
I took this with my iPhone 11 Pro, standing quite far away and with digital zoom. This is not perfect, and I do not expect it to be. But the detail on the tree does not seem watercolor-like. It seems blocky, but that is expected. It’s iPhone, not Nikon, Sony, or Canon DSLR or Mirrorless.
But, look at the difference between these two photos.
Left is iPhone 13 Pro camera app using RAW settings. Right is the same photo file put into Lightroom, with no adjustments made by me. The over processing on the left apparent. Nevertheless, while I don’t have a good flower comparison at the moment because I do not have access to all of my old photos:
This is from the Lightroom version, and it still is not as clear as photos in the past have been.
