It only really does anything if the pixels can turn off completely. So the dark theme would have to feature full black backgrounds, not dark grey or anything like that.

That's not true. You can go upwards to 33% grey and it'll have the same effect as completely black if I recall correctly, but the all around energy saved by using dark mode isn't anything to write home about, really.

The Purdue study found that switching from light mode to dark mode at 100% brightness saves an average of 39%-47% battery power.

That's a lot actually. Only that much outside on sunny days, but still.
