The interesting thing about UV-LED lighting is that it could offer much higher CRI at higher CCT.
In normal white Nd:YAG phosphor LEDs, it is just a narrow blue frequency spike stimulating the yellowish phoshor, so all the CRI is concentrated in the longer wavelength, lower color temperature, side of the spectrum. But if we look at the graph of some of the common enhanced color fluorescent lamps, we can see a wide phosphor hump in the blue-green part of the spectrum, in addition to a small spike on top of that at around 486nm.

I am not exactly sure what this phosphor is, but it does a great job of creating a broad hump of frequencies in the blue-green part of the spectrum. This is exactly a part of the part of the spectrum which normal white LEDs are deficient in. Now let's take a look at the graph of an enhanced spectrum LED lamp, which has a separate red frequency emitter chip:
Just imagine the CRI that would be possible if an LED lamp used three separate chips, a normal white phosphor chip, a red frequency LED, and a violet chip with that blue-green phosphor.
