I have an autoimmune disease and binocular vision dysfunction and have been using my iPhone 13 on iOS 15 for the past 4 years with no issues. The other day I accidentally disabled True Tone from the control center Lock Screen and ever since the phone has been very fatiguing to the eyes. I’ve researched and consulted every source I can think of and everything I’ve read indicates this should not cause a problem. Yet it appears something has changed.
Does anyone know if this is possible? Does True Tone interact with the Auto Brightness curve and is it possible this has somehow been reset? Does True Tone “learn” over time like auto brightness? Prior to this low power mode never bothered me, but the display seems more uncomfortable with it on now. I know the OLED iPhones use PWM, so perhaps something went awry.
I know this is a very obscure and technical question, but other users recommended I post here in the off-chance someone can help me out and if there is a way to “reset” things back to how they were previously (whatever that is).
And yes, I know iOS 15 is very old. Given my health issues, Apple Accessibility recommended I do not update the OS of my main device because of changes to HDR and temporal dithering in newer versions of iOS. I am aware of the security vulnerabilities, but I don’t put anything sensitive on the phone and it’s a small price to pay to be able to look at the device.
