It has an LTPO display, but only down to 10Hz (Apple Watch can reach 1Hz, which I guess is the reason why iPhones didn’t get AOD). That “notification area” rumor sounds very sketchy, I hadn’t even heard it, not at least from Gurman et al. Astrophotography wasn’t explicitly mentioned, but you can do it — they even showed one image with long exposure in the keynote.
I’m not saying they didn’t have a high rate of errors this time (esp. with the watch), but many of the rumors they anticipate are way beyond what you can guess with no extra information.
