Not all light is the same.

Visible light. Natural light spreads its energy fairly evenly, from violet to red.

LED screen light. An LED screen doesn't. It concentrates its energy in two peaks, right on blue (380-500 nm) and green (500-590 nm): the two harmful bands.

Yes. Balance filters only the high-energy bands and lets the rest of the spectrum through, so colour and contrast stay. It's not a tinted lens that darkens everything.
