228w - total system draw with LG C1 off/standby 270w - #000000 fullscreen 332w - #FFFFFF fullscreen 270w-228w = 42w #000000 fullscreen power draw 332w-228w = 104w #FFFFFF fullscreen power draw ( 104w - 42w ) / 42w = 2.4761 so ~248% more power usage from the screen for full #FFFFFF. One thing to note is I have the OLED pixel brightness set to 50/100 and the brightness set to 50/100. 2.2 Gamma, black level: full. The LG C1 has some auto brightness baked into the firmware and it fluctuates, I tried to measure it at full brightness but as you can see today it's at 62w over #000000 compared to before so there is some deviation. However, I think it's safe to say that darker colors do actually save substantial power on OLED displays. Plus the black levels really are just amazing. Black is actually black and not a weird grayish with backlight shining through like TN/IPS LCDs. edit: formatting.
