That said, speaking about, let me say "facts". Dark mode in LED screens is useful because of this: LEDs get lighted up to display white, and cast rays of light directly from the screen to your eyes. That is what is annoying and tiring to your eyes. Using dark mode, that essentially turns off most of the pixels in the screen works because: 1. The light emitted and cast to your eyes is sensibly less; 2. Saves battery (less leds turned on)
But, on e-ink screens, nothing of this is true. Pixels here are just "balls of ink", turned on the black side or on the white side. None of them do emit any light. Light comes from the leds in the bezel of the kindle, and those leds are turned on anyway, whether you use "bright" or dark mode. So the e-ink pixels do reflect the same light to your eyes, no matter the color they have.
Okay, black pixels will reflect slightly less, but not that much. Which is why in dark mode (expecially in a dark environment) you still have that "glowing" look if you look at the dark-mode screen of the kindle: you still are seeing the bezel light being reflected back to your eyes.
So, while dark mode in oled screens means "screen not emitting light", it doesn't in e-ink front-illuminated screens, which is why dark mode makes little sense, physically speaking, on the kindles and on your eyes.
As I said, though, you are absolutely entitled to prefer it, as it is a matter of tastes; it's just that, well, physically dark mode is not different than "bright" mode.
I for myself, I don't like it because the glow becomes much more apparent on a dark screen. Moreover, I also see many more fingerprints on the screen when it's black.  |
The backlight on the Kindle PW appears to be somewhat reflective, as the LEDs illuminate the text, which reflects to your eyes. Dark mode would reduce the total amount of light leaving the device, and potentially reduce eyestrain if it helped the device match the background brightness of the room.
It doesn't save power, though, but it's entirely reasonable that it may be easier to view for some people.
