Do 3rd party camera apps take photos differently from the stock camera app? Do any of them use iPhone's "stocks software processing"?

By stock software processing, I mean whatever processing is done to photos when taken with the built-in camera app. I'm done really care about picture quality but I'm curious. I'm thinking of switching to another app if it can save Photos as files on iCloud.

I would rather see the opposite. Cause sometimes native camera post process makes photos unrealistic
also if there would be greater lens distortion correction bc sometimes if you capture photos of oeople and they happen to be on the side of photo their limbs tends to be shorter or longer disproportionally.
