I spectrum analyzed both CFD and LED lights and neither carry anything resembling a full spectrum. They just appear white because the frequencies they emit trigger all 3 of our color receptors.
Basically they have the same problem - converting either deep blue or ultraviolet light to lower frequencies by fluorescence, but each component in the fluorescent dye only produces light of a single bandwidth - one color. You need a rich mix for a good spread.

That said, normal incandescent bulbs lack in blue and purple. Even a 'warm' colored LED brings out blue details better than the old stuff.

I replaced my last CFD lamps with top tier LEDs - finally some that outperform them in lumen and don't fail within a month or two... and they only get lukewarm, where the CFD's got scorchingly hot.
2011 Honda Insight + HID, LEDs, tiny PV panel, extra brake pad return springs, neutral wheel alignment, 44/42 PSI (air), PHEV light (inop), tightened wheel nut.
lifetime FE over 0.17 Gmeter or 0.1 Mmile.

It always takes longer than you expect, even when you take into account Hofstadter's Law.

When I drive a car I'm a driver. When I'm sitting on my couch I'm a biker.
