I agreed with you but a true low brightness setting while maintaining contrast is hard to dial in. Also, due to either the driving electronics or LED diode physics sometimes the back pane initial brightness at 0br+1*dbr is too bright (lol or lumens instead of br), for instance on my macbook pro at night lights out darkness. For instance with OLEDs there is a turn on voltage, where either the pixel is Off or On at this initial brightness. That goes sufficiently dim on my phone with an OLED screen. I suspect the back pane LEDs have this same minimum brightness at minimum voltage. An OLED laptop or desk monitor would be nice but I don’t have that money.
