I usually completely ignore the Low-Blue light feature, because that particular feature is completely moot if it has RGB colour control
Actually, it's useful for late night usage, as blue light interferes with circadian rhythms. Those who have trouble falling asleep should try limiting their exposure to blue light, prior to bedtime.
And "blue light" doesn't have to be light that
looks bluish. It's just the blue spectral component of any light. A white light counts, for example, as it necessarily contains some blue.
