I remember a long blog post about it on f.lux comparing it a bunch of competitors with actual measurements rather than pure RGB values.
Of course LCD doesn't turn on any pixels, it just stops blocking the white light from behind the panel, but the result isn't any different.
Unfortunately I can't find the link right now, I must've read it a decade ago. Perhaps it's been lost to time.
The end conclusion was that a bunch of free apps/cheap software thought they could get in on the blue light fad and turned the screen redder without significantly reducing the amount of blue light transmitted. At the time, there were one of two kits of software that actually showed a significant drop in blue light because their colour mixing algorithm/colour profile adjustments were done correctly whereas the competition just implemented it wrong.
