Raw isn't really a format unless you are referring to CSI packets or something. It's just the values coming off the sensor. Those values are heavily dependent on the design of the sensor. There are significant non linear characteristics in those values and each camera has hw/sw to account for that sensors characteristics. It is very difficult to make two different sensor models that will provide the same exact value for a scene because they way they capture the scene is electrically and physically different. All those algorithms the parent is talking about are custom made per sensor generally. The ideas are the same, but they have to be tuned for each sensor and as the parent said, it's incredibly subjective and every company / vendor approaches the problem differently depending on use case.
