That's exactly correct. The colour temperature of the reference white (ie; the WB) is vitally important for correct colour rendition. The eye will adjust to an incorrect WB, but it will still be incorrect.
It's just as likely that, as you said, a salesbunny wound up the colour control to make the image "look better". Go knows that it's common practice in showrooms.

And the Spyder will let me set up my Pioneer Kuro correctly? Because that's what we were discussing.
I already have a huey, which did a decent job on my computer monitor.
The overlap is caused by the shape of the standard observer curves and is part of the very reason that using a narrow band RGB device may not produce color properly. The CIE standard observer curves are precisely attempts at modeling the response of the human visual system. For decades, cameras have been calibrated to match them, and phosphors designed to do the same, to the degree possible. Now, with narrow spectrum devices, we have to consider the implications of those assumptions. It may be that in the future, we should simplify the system and use a narrow band response in cameras and reproduce the RGB in the same manner at the display. Then we can more easily predict the output of RGB systems using a standard matrix.

My experience with the spyder products and other tristimulus colorimeters such as those from xrite and sencore (really just a version of the xrite products) is that they are a poor choice for anything other than gray scale. If you want to adjust a CMS properly, you need a spectrophotometer. The minimum useful would be the i1 pro.

Thinking about this offline leads me to realise that there is a fundamental difference between the operation of a slide and the operation of an LCD display.
A slide consists of a series of coloured dots (CMY) mixed together in such a way that they filter out some of the colour, and leave the rest. A red dot will be produced where the G and B have been filtered out, and only the R left.
An LCD consists of ADJACENT (not overlaid) coloured filters. So a red dot is produced by having the B and G pixels opaque, and only the R one (which always has no G or B) letting light through.

In that case, you might be able to rig up some way of using it on your Pioneer.

The problem with LCD monitors is they typically only have 6 bits (64 levels) of resolution for each colour channel, so you don't have a lot of scope for tweaking the WB via the LUTs. Do it that way, & you'll lose tonal detail, resulting in posterisation.

Uh-huh.
There's no such thing as a 5000K LCD display, sans backlight. Until you put light through it, an LCD doesn't have a colour temperature at all.
Yes, it does. It drastically reduces the number of transmission levels available to the pixels of that colour, causing posterisation & colour distortion. The more out of whack the colour temperature of the backlight is in comparison to the desired colour temperature of the image, the worse the problem will get. Unlike CRTs, the transmission value of an LCD pixel isn't infinitely variable, they only work in steps.

Exactly. It's why CRTs are better than LCDs for editing photos, for example.
