It's been popular for years among some developers, largely for that 
retro CRT VT 100 feeling. Personally, I blame The Matrix!

Research suggests that dark mode reduces the amount of blue light we're 
exposed to, and blue light stimulates us, thus making it harder to 
sleep. However, based on what I've read and my own experience I'd say 
this is humbug for any kind of LCD display, because the backlight always 
produces blue light. On OLED screens you **can** get better energy 
efficiency with dark mode and, because there is no back light, you can 
reduce the amount of blue light produced because the display really only 
lights what it needs. So, I've had dark mode on my OLED phones for most 
apps for as long as possible, though it doesn't work so well for maps.

However, any kind of self-illuminating screen is far more stimulating 
than other screens. This is why e-ink is **so** much better for reading 
than LCD or OLED, especially at close distances. Whether my Kobo is blue 
or orange is far less important than the fact it make use of ambient 
light.
