I have noted that both my old iPhone 11 Pro and the iPhone 12 Pro Max tend to shoot a little ‘green’, but I’m shooting with light filtered by a plate glass window and light box diffusers. I note that in your first images, I can see the greenish tint, but the light is also considerably filtered or diffused by clouds where in the third image the sky is clear. It also depends a lot on the time of day that I‘m shooting, and these images seem to be taken at different times, and maybe seasons.
I’m inclined to believe that what we’re seeing is what’s really there, unfortunately our eyes/brain compensate for color shifts extremely well, for example making subjects in both tungsten and fluorescent lighting appear natural after a few minutes, until we make images and compare the images.
Adding about 10 points of magenta to many of my naturally lit light box images is a routine thing though. I process on iPads and my old Gen 1 iPad Pro is considerably ‘greener’ than the Gen 3 iPad Pro so I have to watch that too. Photography has been a hobby and avocation for decades, and getting a finished image to look like what you think you saw is a never-ending part of color photography. If it makes you feel any better, the color casts from different brands of film were far more pronounced than with digital sensors, quite often you would choose a film based on the subject or time of day.
