Seems to be en vogue these days. Energy saving? Imaging how many KWh and thus CO2 you can save in the world when every window background color is dark grey instead of white :)

LCD displays won't save energy with a "dark mode", certainly not unless it's dark enough overall that a "smart" display could reduce backlight intensity and adjust the pixels accordingly - and AFAIK, that's rarely if ever done (maybe in sectors on really large TV screens), and would be hard to get right.

An OLED display (or some other that had self-illuminating pixels rather than a backlight filtered by the pixels) could save (some) energy with darker images.  But aside from a few phones, and very very few TV's or monitors, that's still very scarce.  Perhaps if OLED or similar displays become common, that will be a realistic consideration, but IMO, it isn't now.

If dark mode has a point, it's reduced eyestrain, paying more attention to the work than the doodads, and accommodating different preferences or visual limitations.
