RAW files. Even then, you mostly see the processed result based on whatever processing your raw image viewer/editor does. But if you know how to get to it and use it, the same raw sensor capture data is there
Most cameras will let you export raw files, and a lot of phones do as well(although the phone ones aren’t great since they usually do a lot of processing on it before giving you the normal picture)
My understanding is that really raw phone data also have a lot of lens distortion, and proprietary code written by the camera brand has specific algorithms to undo that effect. And this is the part that phone tinkerers complain is not open source (well, it does lots of other things to the camera too).
My own unprocessed RAWs are pretty wild. But (IMO) it’s a reasonable compromise to make lenses cheaper and better, outside of some ridiculous examples like the 24-50.
How do you get a sensor data image from a camera?

Modern mirrorless cameras do this too. For example, this is what my Canon kit lens looks like with/without digital barrel distortion correction:
