On top of that, even the "warm" color temperature LEDs put out a pretty good spike of blue light. I'm working on some analysis of this, and even the "warm glow" sort... yeah, there's a ton of blue. Right in the realm of spectrum that convinces our body it's day.

So I'm not sure that the whole color shifting makes a big difference if you don't get rid of the blue as well. White LEDs are generally blue LEDs with phosphor coatings, but they still leak the blue. It's quite annoying.

I've been going back to incandescents and they're properly nice in the evenings.

I find most "2700K" LEDs sub-optimal. Helped someone set up their office recently. It was too dark with 1 bulb in each of the 3-bulb ceiling fixtures (48" fluorescents). We found 48" 4000K LEDs in the ceiling fixtures. She found 3000K tubes (GE? Feit? Philips) at the home store. They're quite pleasant, much better than other 3000K bulbs I've been around.

I have some Citizen "CITILED Amber Color COB" on top of my kitchen cabinets. They have a little hump in the blue portion of their spectral graph, but are fantastic. Rated at 2200K

Also have some Amber Philips 2000K bulbs, which are quite nice.

That's what I figured. LCD monitors are all painful for me to look at as well.
