I think the answer is that it's not entirely the truth.  Tungsten filaments act like black body radiators, and there is a specific spectrum associated with it at a given temperature.  LEDs are not black body radiators and have weird peaks at different frequencies.

The Color Range Index addresses exactly this.

There is more to it than just Color Temperature - there is also Color Rendering Index which measures how faithful the light source is able to reflect colors and related to how even the light is through the color spectrum.

From that reference it appears that LED's do pretty well.  

As @gunrunnerjohn noted, good LED assemblies can get very close to an incandescent (some of the inexpensive ones are lacking in this).
