Why does the iPhone 11 Pro take much better 4K video recordings than the iPhone 14 & 15 Pro?

Have you noticed the terrible quality of photo and video recordings with the camera of the latest iPhones?
I want the foreground and background to be as sharp as on the older iPhones.
11 Pro were the last good iPhone cameras, except for the RAW 48MP setting which is the only good thing about the newer iPhones, but everything else was beyond terrible quality, even the zoom lens has terrible 4K video recording quality 🤮

I HOPE Apple brings 8K video recording to the new phones 😭 I really need it even if it’s exclusive to the 16 Pro Max. I hope they listen for once. I would be beyond grateful if they would make it possible for us.

Do any of you know how to make an app that will allow us to film in 8K if Apple doesn’t let us? I’m dying for such a feature. I’m practically begging for it on my knees.
