Anecdotally it seems to have got worse in the past few years. I don't know much about photography, but it feels like the software is far too aggressive in its desire to capture dynamic range, and generally unwilling to let areas naturally be in shadow. Many of the photos I've taken on the last couple of iPhones look flat and unpleasing, unless it's a bright sunny day. Which, given I live in the UK, is something of a rarity. Maybe the algorithms are tuned for Cupertino.
My wife has been using Google Pixels since the original—while it lags behind in video capture, imo, I've always preferred how the still photos out of her phone look.
I was really excited for the 48MP sensor in my new iPhone. Initially I shot a lot more photos and tried to use it more like a 'real camera,' but I wound up picking up 35mm photography this year. I'll likely get a digital body eventually too, but I'm enjoying learning about film stocks and getting a really deep understanding of the exposure triangle. My fancy new iPhone camera ultimately just pushed me to realize I want to be shooting stuff that can enlarge and print better and it's still not there. Not to mention the optical effects of a "real lens" (bokeh, true and configurable physical depth of field).
