"As an example, one commercial QVGA OLED display consumes 0.3 watts while showing white text on a black background, but more than 0.7 watts showing black text on a white background, while an LCD may consume only a constant 0.35 watts regardless of what is being shown on screen."

The citation was from 2009. I expect, or rather hope, that things have improved. Interesting link, by the way, and very useful to add to the discussion.

So it depends on the display and may become a thing of the past.
That's really good info.
IIRC, the two primary things we did to conserve battery power were 1. Avoid certain games and 2. Turn down screen brightness.
In ordinary usage, the screen on our tablets was typically the biggest drain on the battery. This was especially true for tablets with a large screen.
I don't have (anec)data specific to dark mode on websites and power usage. I just know that using our devices carefully was the difference being kept occupied for three or four hours until we could sleep or running out after an hour and having nothing to do but talk, which is not a stealthy activity.
