You’re over simplifying. All sensors will do some amount of signal processing before the photosite readouts are written to memory. Lots of people assume RAW means just that, but raw usually just means pre-debayering. There may still be some amount of noise reduction applied prior to this step. This was a huge deal for Sony sensors and astrophotography for a hot minute.
