I have a 2016 SE. The problem isn't the display type, but the manner that Apple implements the screen dimming. Your computer screen probably flashes LEDs on and off over 1000 times per second to simulate dimming. A desktop monitor might do 10,000 times per second, or even use DC dimming which doesn't flash the LEDs at all. The iPhone 12 mini has the lowest flicker rate of around 272 times per second, which causes eye strain for me. That's not a feature of an OLED or IPS display, it's just the manner which Apple chooses to implement it. While I hope that I can get a 13 mini with a screen that doesn't irritate my eyes, miniLED by itself isn't a fix. :\
