As others have mentioned the AOD can be turned off, and I know that you posted about your reasoning. I just wanted to also mentioned that if you have your phone in your pocket, face down on the table, and (if you have a Apple Watch) if you leave the area the AOD will turn off. The AOD is not exactly literally always on unless you just have it say propped in front of your desk in which that person can make the decision to either turn it off or keep it on. Also remember that AOD can also be managed with focus modes so if you have it off during "bedtime" like my focus mode the AOD is off during the night.
Using the term "much lower" is very misleading/incorrect. In the first part yes it is lower but not by much like you said we are literally talking millimeters, but technically your second part is wrong because the new pill is smaller so how is the effective area smaller than the notch? if something is overall 30% smaller how is the effective area also smaller?
Camera noise well you didn't put any kind of settings or tests you did... is this is proRAW and how were you doing side-by-side comparisons?
Price? depends on the market you are in because for U.S. it is the same as last years model, but you also did not state the market you are in.
It is that much lower
The notch is lower then the rectangle under it is smaller, not hard to understand
