>unusual for a phone to overexpose highlights
Although this is really quite recent. It used to almost be a hallmark of my iPhone that, unless I took care, things like clouds would be blown out. I was somewhat prepared for this as I mostly shot slides pre-digital for a long time after I didn't have easy access to a good darkroom any longer. And slides don't handle over-exposure well at all.
In a way the iPhone and recent HDR techniques on smartphones improve on this as it's now quite unusual for a phone to overexpose highlights. The tone mapping could be improved to lessen that 'fake HDR' effect you can see in your examples, but that doesn't seem like it would be too difficult.
