None of your reasons cover the hordes of people buying the pro models when there’s absolutely no reason to. Especially in India. I live in an upper middle class apartment complex and half the folks living here have a 13 Pro. It costs 60% more if not higher here than in the US as well. You have to be in the 99.5th percentile of salary earners to cover the price of the phone in a single months salary.

It’s all about image and prestige and that’s one of the biggest reasons nowadays if you ask me.
