Sorry, it doesn't answer my question. You are not reading carefully.
Color temperature is controlled by three hue controls (some monitor just have a single temperature control, while others have individual hue controls that make up what is known as temperature). Adjusting the ratio will give different tints, but what if you kept the ratio constant and just increased or decreased all colors at the same rate? What is happening when the ratio is controlled for? I've noticed that tint looks the same, when ratios are constant, but the whole image looked brighter or darker depending if you increased or decreased the hues at a constant ratio.
I was hoping you could answer my question as you are expert, though your aversions suggest otherwise.
This statement is ambiguous.
"At this temp, with the contrast set at max, the monitor luminance output is max"
Are talking about the contrast, temperature, or both as contributing to max luminance? If it is either the temp. or both, then you are saying that color temperature does indeed at least contribute to increase of the luminance, and therefore will technically increase screen wear, much as just turning up the contrast (white) will. What if the color temp is low (for each of the hues)and contrast is set to high? Will the monitor luminance output be less or more that scenario you described? If less, then, assuming by luminance you mean the increased emission of light by the phosphors, you have to admit that increasing temperature, to what significant degree unknown to me, will affect negatively affect the phosphor life relative to decreased temperature (assuming all else equal).
The statement below is not true strictly true if I understand it correctly.
"When you change color temp and want a more reddish color, the monitor simply decreases the beam current that hits the blue and green phosphors"
5000K is reddish, but the red hue in absolute value lower than in 9300K, though in proportion to blue and green is higher to 9300K! I have a feeling you are not so familiar with the component nature of temperature color, or else you are deliberately misleading.
Now, it could be that each component color control doesn't affect one color, but that it controls a ratio itself, namely subtracting other hues to relativley raise its own hue. So increasing the red hue, is in fact lowering the green and blue. Let's say it's by -1 each per hue. If this is true, then increasing blue and green by the same amount will actually result in r of -2, g of -2, and b of -2. The ratio will be the same after increasing the hue by the same amount for all component hues, but since it is subtractive for "adversary" hues, the overall luminance has gone down! Isn't white light based on combinations of r, g, and b and doesn't increasing the luminance of the hues at the same rate increase in a brighter white (of the same ratio)? By your explanation above, the highest temperature will will result in the lowest luminance.
Maybe you could just answer this one repeated question.
When adjusting the hue (of which three make up "temperature"), what physical parts of the monitor of the involved (please, talk about cathodes, phosphors, or whatever is relevant) and how do they change?
Again, I value your expert knowledge for my selfish curiosity.
