Is that correct? Does #010101 use the same energy as #FFFFFF or do darker shades still use less energy?

#2I'm guessing it's a combination of yes and no. OLED screens save power on black colors because it can completely shut off the pixels responsible for illuminating that portion of the screen. If you have a slightly brighter color than pure black, the diode will turn on but not at full-brightness.
Technically speaking, you probably stand to save the most power on a purely black background. You're still saving power on other dark colors, but it's probably more noticeable with pure black.

Is #010101 effectively #FFFFFF or does it actually use less energy the darker it is? With LCDs we know it is the former, but what about OLED displays?

#8Mind you most "dark themes" in computer programs aren't using 100% black, but some shade of grey or green.

#9I mean the display panel A might be 20% more efficient than display panel B, but connected to a power supply that is half as efficient as B's.
Good luck.
