    FYI ereaders don’t emit light even with the light on. They use lights hidden on the sides under the bezels, and that light gets distributed above the screen using a kind of gel layer. The screen then reflects that light back.

      Isn’t the device emitting light though, if not the screen itself? I don’t know if there is a technical definition of “emit” that is narrower, but I just meant that there is one time where the device itself is the brightest thing in the room and dark mode reduces that.
