I've also read that it takes more power (battery) to render black than it does white. Combined with the need for more brightness it doesn't seem like a good solution.

Calibrating my monitors took them from having piercing bluish whites to more softer pinkish whites and reduced daytime eye strain significantly.

I then use Redshift at night with the undocumented "preserve" switch to combine my icc profile with the Redshift changes.

This really depends on the display technology and for more modern monitors, the opposite is true.

Very few monitors use OLED, and most phones don't either although it is becoming more common there.
