Please note that I'm really not trying to proclaim one direction of color temperature over an other; mostly, I'm attempting to proclaim that while OP's observations may be inarguably correct, his conclusions are without basis in fact and are unsupported by even his own observations.
For my own opinions: A dozen or so years ago, I saw an outdoor Rammstein concert in Cleveland, Ohio, which was at a time where stage lighting predominately consisted of approximately sixteen million halogen PAR cans.
Rammstein likes very white light on their stage.
Accordingly, the vast majority of this plethora of cans had a light-blue gel over them, making them appear to be very, very white. (Glistening white. Fairy-tale white. 7000k white, in a time when lights were never 7000k.)
Except for one stray can where the gel was installed wrong and fell out or burned or was missed or somesuch thing, which in comparison seemed to be unnaturally yellow.
It was a brilliant show; the best I've ever paid for, both in terms of music, theater, and performance. That one yellow (aka open halogen) light still hangs in my mind as the flaw.
But, back to color temperature, that was the intent: Rammstein is not exactly easy-listening, and they very purposefully chose a lighting color to force the audience to be alert and awake -- even though it had real tangible costs in terms of space on trucks, generator capacity, cabling, and/or overall luminance.
My own opinion is that higher color temperatures have their place. One of my employers has a showroom with a lot of east and south-facing windows, so it gets quite a bit of natural light. The owner upgraded from halogen PAR-30 halogen track lights a couple of years ago to 7000k LEDs on the same tracks, and it's a positively lovely thing during the day at any time of year: 7000k is not so dissimilar from the oxygen-filtered blue that we get with ambient sunlight.
But in the winter months, when the sun goes down early, it looks positively dreary in the evening before the shop closes...and for a couple of hours a day, for a few months a year, it would be better if he had lower-temperature lighting.
My own garage is another good example: I tend to prefer "warm" lighting after decades of actually paying attention to color temperature*, so I've got it lit with warm Cree LEDs. But my garage is windowless, and in the winter (when the doors are all closed) the Cree LEDs work great.
In the summer, with ambient light streaming in from both the man-door and the overhead door? Not so much: My LEDs -will- appear to be artificially yellow in that environment.
*: When I was younger, the hottest non-flickering white one could get was halogen. I liked it quite a bit. Later, I discovered that I liked dimmed halogen better. Later than that, I discovered that my television's default settings were very wrong, and learned how to calibrate them using the service menu and a colorimeter for a picture that is much softer and much more...brown than most people expect, but which matches the same broadcast standards that the studios use and is therefore more accurate. Later still, I actively hunt down improperly-placed high-color temperature lights: When I moved into my new house a few months ago, one of the first things I did was remove the blue-ish CFLs lighting my basement/home-theater room and replace them with -anything- warmer: It is now warm LED-lit, with some Cree and some Wal-Mart Great Value, and everyone remarks that it is the most-evenly lit area of the house despite the giant fucking windows in all rooms on the first floor**.
**: Which are lit with chandeliers with 5ea 25W flame-shaped incandescents. Which the landlord insisted that I keep the same, forever. And for which even provided a packaged retail example of to make sure that I knew what bulbs to buy for replacements. And which my lady-friend actually likes. I installed cheap Lutron rotary dimmers to try to take advantage of zero-crossing to be nice to the filaments (which tends to make tungsten-filament bulbs last years instead of months), and also to be able to turn them down to save energy while also providing navigable light***.
***: Even if that dimmed light is far more warm than I might like, it's still just fine for navigation and saves as much money and materials as I can given my stated constraints.
****: As an unreferenced footnote, I will check out your link, though it sounds like something that Rammstein's lighting engineer figured out over a decade ago. Likewise, you might want to check out the Imaging Science Foundation, fl.ux, and see if anyone on avsforums has an ISF-based calibration model for your television. You might be surprised, but then you don't seem like you are basing your conclusions and predictions on the utterances of others (minor children or otherwise).
