Sorry for getting to you a little late
@Bradley3647, but have you tried emptying the cache on your camera app via the home screen?. This can be a good way to rid your camera of any bad habits that it is developing. I have just been testing my S23 Ultra out, and there is no green bias going on to my eye, either in videos or photos. Yes, the colors pop a bit, but that is how I like it, as I always have my display in vivid mode. If you have your display in Vivid mode, how do things look for you when you reduce your screen to Normal mode?. My last question is, do you have this over saturated greens issue when recording videos also?.
