what's it called? searching Settings for "pulse", "width", and "modulation" all produce no results.
The setting is called "display pulse smoothing" (the description says it WILL disable PWM) and is available in iOS 26, not sure about earlier versions.
Settings → Accessibility → Display & Text Size → Reduce White Point
Also Display Pulse Smoothing (PWM) if you're on Tahoe.
