"The problem I see with most LCDs is the color temp due to the LED
backlighting. Everything is way too cold (blue). Except for that, just
peek in a bar with multiple TVs, they're not perfectly matched, but far
closer than in the days of CRTs or plasma stuff. There's no phosphors or
electron guns to weaken at different rates."

Most of them now have user color temperature adjustments. That will be at the highest setting when it leaves the factory.

The LEDS are chosen for the high blue output because to use the display to lower the color temperature is much cheaper than to raise it. In terms of brightness. And it does not react as well as CRTs did. But in both, if you DO want higher color temperature you need to boost the blue. Reducing the red and green is not the right way to do it.
