I am particularly sensitive to PWM/LED light flickering. I was recently in a hotel, and the WC was lit with some extremely dim, low-frequency lighting. I waved my hands in front of my face, and could easily make out a stroboscopic effect. PWM flickering gives me a massive headache, and I really wish manufacturers would use slightly more complex circuitry to give out a constant light (whether display, or household lighting) at different brightness levels. I also dislike 60 Hz displays for this very reason. We should definitely normalise higher refresh rates for displays throughout, from smartphones to monitors.
