>LEDs being relatively bluer than incandescents or common fluorescent phosphors

There is nothing inherently bluer about LED technology. LEDs are readily available in color temperatures down to 1600K.

This isn't correct. Most white LEDs use a blue LED which is shone on some phosphors which then emit a broader spectrum of yellow light.

The ratio of yellow to blue light determines the colour temperature perceived. Some of that blue light will always get through, so white LEDs (even "warm" ones) will always have a blue light component to them.

Exactly. There are plenty of great quality LEDs around that emit beautiful, warm light and have absolutely no flicker.

But LEDs get a bad rep because there are so many garish blue-white, flickering, junk ones flooding the market.
