iPhone 14 Pro Max Headache and Nausea

I recently got an iPhone 14 Pro Max and have been getting intense headaches and feeling nauseous whenever I look at the screen. This has never happened with my 12 Pro Max and has only come on since using the new one. I have turned off “True Tone” and have also turned on and off “Reduce White Point”, and have had no relief with either attempt. Is there any other setting that I should try adjusting?
