It was always kind of a scam. Computers always had color temperature settings. It is a sad fact that they use to all be set to around 9300K color temperature which is very unnaturally blue. Best color rendering is actually 6500K and people like me always reset them once purchased. You can also set them lower then that too say 3400K too.
Reason device makers used high color temperature was showroom. Two displays side by side, the lower color temperature will look yellow and no one will buy it. All about customer manipulation and marketing. As an engineer this always bothered me. Sell something not configured correctly to get the sale.
The one way lower color temperatures are better is that the eye is not as well corrected in the blue so vision should indeed be sharper with Amber sunglasses for example. There is some science behind that. Same for sleep issues. Lot of the other stuff seems more marketing and questionable.
How? I have a new monitor with a panel that is pre-set to reduce eye strain paired with one that is absolutely trying to look good on a show floor. So flux is great for the old monitor but makes the new one un-ignorably orange.
Yes. They both should be set to same color temperature. If both set to same they both will look white. If not the lower color temperature will look yellow or maybe even orange. Eye color perception is largely relative and adaptive.
So my monitor has a setup menu. I open that. Select color adjust, then select the setting. My setting options are sRGB, 9300K, 7500K, 6500K, 5000K, and User white point setting. Lot of monitors are set by default to 9300K which is way blue. SRGB or 6500K is most color correct and both 6500K color tempetature. Mine is actually set to 5000K at the moment.
You mentioned flux. Screen brightness is usually set by the contrast control and the brightness setting is usually to set the black level. Yes, I know strange.
