I'm not sure I would agree with that assessment. If I could get closer to
5000K, why wouldn't I want to?


Again, 5000K is a LOT of differing colors. Which do you want? If you look at the lines of correlated color temp on a CIE chromaticity diagrams, those colors range widely from a magenta to green axis.

This is one reason why the CIE defined the Standard Illuminants.These illuminants are defined spectrally meaning a certain amount of energy at each wavelength across the spectrum. This is an exact and non ambiguous description of color. D50 is an exact color, it is not a range of colors. A color whose CCT is 5000K is not unique as there are infinitely many different xyY and SPDs that share it.
