There's a whole GCam (Google Camera) modding community that manages to get image quality that's often better than what non-pixel OEM vendors offer. These ports usually work on LineageOS (and other ROMs) This site has a large collection of models and the config files generated for each device: https://www.celsoazevedo.com/files/android/google-camera/ I think they link to some Telegram channels too where people share the kinds of photography they get with the modifications.
