Does a high CRI LED that produces more PPFD better for growing light than 6500K and more than low CRI?

Am I correct in understanding that High CRI LED at 3000K is a better choice for grow light in that it produces more PPFD than 6500K and more than Low CRI? I'm a little confused as the spectrum picture for 6500K looks more like what I see other grow lights showing, compared to the spectrum for 3000K. 

While you are correct that certain warm-white spectra will produce more PAR per unit energy, the additional PAR energy may or may not be better suited for growing.

​At a basic level, PAR tells us about the number of photons that fall within the range of wavelengths capable of inducing photosynthesis. It does not, however, tell us how capable those particular photons are of inducing photosynthesis.

​As such, it can be a bit misleading to compare just PAR values (PPF / PPFD) to determine "how good" a grow light is, as much will depend on the specific distribution of energy across the spectrum.

The 6500K you commonly see is a close approximation of natural daylight, so this is typically seen as a solid reference point for horticultural lighting applications.
