Red Light Screen/Remove Blue Light

I saw the LPII (and any e-ink device) as a way to interact with technology without negatively impacting sleep. With the change to OLED on the LPIII, I'm assuming that won't be the case, but I'd love to be proved wrong. Saw a review mention that the LP team is able to turn off pixels on the OLED screen to simulate a more paper-like feel, though I'm not sure if that reduces blue light per se. Anyone know??
If not, then the ability to replace blue light with amber light would be welcome. This is a common accessibility feature on modern smartphones.

OLED pixels generate their own light, so black pixels emit nothing - there's no backlight like in other displays. When viewing content with predominantly black backgrounds, you shouldn't experience blue light from those areas. However, white pixels still emit blue light as part of their spectrum. I'd like to test this in person, but having an amber mode for warmer whites would be a great addition. Perhaps implementing a double-click function on the wheel to toggle between warm and cool white settings!

I think it'd be awesome to have a "night mode" or something along that line where all the white turns into various shades of red - it's a good idea for sure! I'd love that kind of thing, but I don't know how well-received it would be to the general public. Otherwise, ronan's idea of a warmer white being used at times is also a good idea. I'd take either

.
At the very least, the wheel will make it super easy to turn the brightness all the way down in dark environments.
