How does the Color Temperature Control settings work?

[Loser-P]

Does anyone know how this setting works? I don't think it's altering the lookup tables (vlut).

I'm asking because I've found that having that option checked seems to to a better job of emulating sRGB on my wide gamut monitor when in standard (wide gamut) mode than the sRGB emulation mode on my monitor, at least as far as having the primaries closer to where they should be.

Wanted to know if I'm losing image quality somewhere by using that setting instead of my monitors emulation mode.

BTW my monitor is a Dell U2711

I think you're over-complicating things..

From my understanding, over the course of a monitors lifespan, the LCD/LED backlight will alter it's colour going from a usually neutral white to a more yellow light as it ages (or can depend on the manufacturer of your monitor). I'd guess that this settings allow you to manually pump more blue colour back into the spectrum to re-balance your monitors deficiency. Your monitor will provide the OS what colour temperature the LCD should be, but as you've noticed you can manually override it. Depending on the age/condition of your monitor, overriding it isn't a bad thing.

I have a heap of apple imacs at work and without fail, anything that is between 3-5 years old is looking quite yellow.
