White LEDs aren't quite there yet are they?

Absolutely true, except that this particular TV doesn't use white LEDs in
its 'revolutionary' backlighting scheme. It uses small RGB arrays, which is
why I was questioning whether there was any control over the individual
elements in each array, such that the colour temperature of the nominally
white light that they produce, could be varied. Which would then, of course,
have a corresponding effect on the displayed colour balance. It just seemed
to me that given they have gone to the trouble of using RGB arrays, rather
than white LEDs, the reason for that might have been to get a full(er)
spectrum white.

colour temp can be controlled using the LEDs or the LCD, I'm not sure
it makes any big difference which one.

RGB LEDs would give the same white as a triphosphor&uv white LED, but
with more colour control. The standard 2 colour white LED would be
useless on a 3 channel display. And fwiw bichromic white LEDs have
huge colour balance variation, way outside of whats acceptable for a
display.
