This surprises me. I thought the big power downside of LCD displays is that they use filtering to turn unwanted color channels into waste heat.

Knowing nothing else about the technology, I assumed that would make OLED displays more efficient.

Can’t beat the thermodynamics of exciton recombination.

OLED will use less for a screen of black and LCD will use less for a screen of white. Now, take whatever average of what content is on the screen and for you, it may be better or may be worse.

White background document editing, etc., will be worse, and this is rather common.
