Our eyes have absolutely incredible colour correction, running all the time and so well that we just don’t notice it; except for some edge cases where it gets tricked (eg the whole dress saga, or optical illusions you can find).
At first I had to keep checking the settings because I thought it had turned off. But when I turned it off it looked extremely blue and painfully bright. Even looking at a white screen I can't notice the orange tint at all anymore. It's pretty amazing.
Screens totally should be orange by default.
