It reads zero from eye distance when dark with the backlight down. Here are readings from contact distance:

Dark 100%: 5 lux

Light 100%: 103 lux

Dark 0%: 0 lux

Light 0%: 14 lux

In my HDR mode settings, tuned for bright conditions, it is:

0% PQ: 0.12 nit

0% SDR: 0.2 nit

100% SDR: ~120 nit

100% PQ: 570 nit

It works better in dark mode than your low contrast. The screen does not support local dimming.

I missed what pq and sdr stand for. :(

Someone is going to ask for a wavelength soon, so get ready to calibrate for 450–485 nm :)

If anybody wants to buy me a spectrophotometer, I'd be happy to take measurements. Those things are pricey.

For my part, thanks for the measurements! I do intend on trying this when back at a computer. At face value, not seeing anything suspicious on these numbers. Bottom line, do not run a bright screen in the face. Darker colors do look to help, but so does dropping brightness. If worried about your eyes, do both.
