Those aren't contradictory. DP is via connection to GPU using the high speed lanes and the 2.0 USB is from the A16 chip, which was designed with USB2.0 over lightning in mind from my understanding.
You said something I didn’t even think about: The a16 in the iPhone 15 is last year’s chip. Of course it doesn’t have usb 3.0 or anything else, just the 2.0 speeds it was designed for.
I do wonder, however, if the A17 will retain the new updated usb feature that the A17 Pro has (clearly they’re binning something or other)
USB3 is at this point 15 years old and USB2 predates iPhones completely. Not sure how that is understandable and/or acceptable. It also has nothing to do with main chip, since IO chip is separate.
The IO chip is specifically not separate in the A17
