Speculation only, according to some of the reading I've done, there are many many ways AI can improve images.
Simplest is, scene recognition. Ai learns from huge library of images, and optimizes settings for various classes of objects, eg human, dog, food, buildings, each own settings for exposure .
Then, motion detection and environmental detection, Ai knows whether dark or light situations, or back light or snow situations, and exposure adjustment done.
But most advanced of all is, Ai learns from library of raw and then same raw images touched up. Ai learns how pro touch-up, so when see your images, Ai will decide which touch up method the pro uses.
Also, Ai will help image processor speed up their processes especially scene and focus recognition of course.
Really exciting because all these are top complex to leak out. Even when leak out, very few will actually understand the leak.
