Quick question about PWM sensitivity. If I go to a store and play with OLED iPhone for say 20 minutes, will I know if I have PWM sensitivity or not. In other words, is it possible that I won't experience any issues during that 20 minutes of testing, but when I purchase the phone and use it for longer periods, I might experience the symptoms. It looks like I have to upgrade from my iPhone XR but I haven't used OLED screens before. Considering SE3 and iPhone 12/13 and this PWM question is really important to me. I would appreciate if you can share any of your own experiences or any ideas you might have how to "test" PWM sensitivity. Thanks!
