These have both been taken with the exact same camera from the same location. The one on the left is with the OnePlus camera app, and the one on the right is from a community modification of the Google camera app to work on the OnePlus 12. The Google one looks a lot better because they use super-resolution from multiple short exposures automatically.
The Google camera app does not usually look better without zoom (in my short time testing) and also has a harder time focusing.
IMO the one on the right is over-sharpened, so somewhere in the middle would probably look pretty good.
The one on the left has so much noise reduction the detail is just gone, I remember that issue on my Oneplus 7 Pro, Oneplus can’t seem to figure out their cameras, and their OEM camera app is awful.
