I'm returning my iPhone 12 Pro in part because of this issue but also because the phone is a bit unwieldy. I may get the iPhone 12 mini (keep in mind the "mini" has a larger display than the old "Plus" models). See my comparison of an iPhone 12 Pro on the left and an iPhone 11 Pro on the right. The first photo is with TrueTone and the second photo is without. I would describe the iPhone 12 Pro as washed out such that you don't get a true white, not so much that it's yellow. I doubt this is deliberate because a crisp white is a hallmark of a good display for reading. I suggest that no one waste their time adjusting Accessibility settings. You should not have to use those settings given the cost of an iPhone 12 Pro. Try the swap lottery or return it as I'm doing and see how things shake out.View attachment 974517

The diagonal measurement is very deceiving these days. When watching a 16:9 YouTube video with the Mini you’ll have a bit smaller screen area than an iPhone 7 at 4.63” compared to 5.5” of the Plus. That means 40% more screen area for 16:9 content for the Plus over the Mini.
In fact, the Xs Max and 11 Pro Max only have 1% larger screen area for 16:9 content over the Plus. It’s all about aspect ratio these days.
