Colour on iPhone 15 pro max too warm, can I calibrate it? Maybe even with a colorimeter?

The colour on my iPhone 15 pro max is too warm. Everything, but especially white has a yellow tint to it. And yes, true tone and night shift are off. I tried using colour filters on the lowest intensity and adjusted it to the most accurate color, but even then it's slightly off. It's just too much of a change of color because I can't adjust the intensity of the color change to be even lower. So now my question is whether there is any method with some app or built in feature with which I can calibrate my display color? Even better if it would be possible to use a colorimeter.
