I don't deny what you are saying is true but... For most people, I would say 90% of photos taken are viewed on their phone. Or sent via WhatsApp etc for someone else to view... On their phone. Or uploaded to social media and viewed... On a phone. Maybe viewed on a desktop PC once in a while. So all these things you mention are great but in real life will be hardly noticeable, unless you are someone who takes photography seriously, which I don't think many people do.
If that's the case then for most people, an average potato cam will do. Which is fine if you're paying average money.
At this price point, average just doesn't cut it.
Many people appreciate a good quality photo regardless of its viewed on a phone or otherwise. Phones screens are in general good to excellent on most phones.
On a side note and in general, personally I dislike most phone cams as they go too far with sharpening. A tell tale sign that it was shot with a phone and not a dedicated cam. And it's something that's easy to add with editing but hard to remove.
I get it's all preference and each to their own. There is no right or wrong.
