This just crossed my mind, and these things do keep me up later at night.

AS far as I know all LCD ISPs are RGB correct.

SO if Pure whites RGB Value is
R 255
G 255
B 255

And pure black RGB Value is
R 000
G 000
B 000

SO if you have a solid WHITE background or a BLACK background, Which will use more energy?

Doesn't matter. The LCD crystals do not emit light. There is a backlight behind them that is on regardless of the color on the screen.

LCD TVs with LED backlight and local area dimming might theoretically use less power when displaying black areas, but I'm not sure that feature has ever made it into monitors.
