But then most dark modes aren’t pitch black. I guess it might save a bit of power by just being at a low brightness. Anyways I need my dark mode and also night mode.
Fun fact! Many OLED displays dim the whole image not by making the diodes dimmer, but by pulsing the diodes fast enough to match the desired brightness of each pixel.
You can test this by taking your OLED phone, pulling up an image, and then waving it around at different brightness levels; the observed image would become blurry at high brightness levels, but would separate into distinct “frames” at lower brightness.
I’m not sure if every OLED does this; just from the phones that I have used.

Less brightness means less light emitted by the diodes means less power is used. They may not turn off, but they still use less.
