That's kind of weird, since the sensors and lenses in the Pro phones are physically, actually better. Like, not subjectively, there's just more light being collected by better lenses. And the Pro phones have an optical zoom system that the regular phones don't. I'm also pretty sure you can't do macro photography without a pro phone.
And, look, only 45% of people are going with the Pro phones; I expect you're not alone in your sentiment here. The normal cameras are great, and they do more than a good enough job. But I wouldn't be surprised if the tipping point for a lot of the people in that Pro-buying cohort were swayed by the camera, because it IS objectively a better system.
