Color temperature is nowhere near everything. Or rather, it would be, were LEDs actually anywhere near a blackbody in terms of radiation output over the visible spectrum. But they aren't. Nowhere near.

There is no every-day use case where the difference in light perception from an incandescent bulb is different, or even distinguishable without measurement, from an LED bulb. Feel free to try it yourself in a light studio, or otherwise, please cite any studies with modern lamps that conclude that the 'light quality' (by whatever metric) of an incandescent bulb is higher (that is, 'higher' as in 'makes a material difference for normal use cases', not 'in the lab using our spectrometer we measured a difference'). As always, there are people (analogous to 'vinyl produce a richer sound' idiots) who have 'opinions' on light quality, but well, we all know what they say about 'opinions'. In 2015, it's plain nonsense to take 'light quality' as a reason not to use LED light for domestic purposes, full stop.

  The subjective experience of a home lit with incandescents is very different than one lit with LEDs. I don't care if the color temperature is the same. Things just look different. The bulbs cast their light differently. There may not be a difference in "light quality", photons are photons, but if you convert a home from one to the other things will look different, and you may prefer one way or the other. And don't forget about fixtures that were designed to work with clear incandescent bulbs for aesthetic reasons. LED bulbs will look downright hideous in those even when the lights are off. There are people who like how vinyl sounds better because they like the hiss and the pops, not because they fall for audiophile silliness. The same holds for lighting.

    Yes, but being unwilling to spend 1 day adjusting to a different look is a pretty silly reason to continue to run a bunch of spaceheaters in your house that, as a byproduct, happen to produce some light. Particularly if you ever use air conditioning.
