> 1. If most of the screen is not full bright white, (e.g. white text on dark background), then LEDs will have plenty of time to cool down
Note that the display is not an OLED display, but a regular IPS LCD with local dimming zones for the backlight[1]. Thus only the dimming zones not covered by white text would get to cool off.
This also points to another downside of pushing up the nits: it will likely increase the bleed-through of the backlight, driving up the black level especially in white-text-on-black scenarios.
