I do know that some bulbs use a mixture of led's of different colors to make white light. The cree ceiling trophers I have at work, if you look at the top side of them you'll see little light beams of rgb popping through cracks and my cree ceiling cans at home, when you dim them, if you look directly at them you'll see hints of separate separate colored light sources glowing. I can't complain about those cree ceiling trophers, I have ones that are on 24/7 and are nearly 10 years old. You can't tell the difference between those and the ones right next to them that are only on 40 hours per week. Most of your "Edison" style led bulbs use uv leds and phosphorous coatings to produce "white" light. It works pretty well, especially for candelabra style bulbs and has a descent cri since it isn't an led that makes the light but rather phosphorous. Similar to a fluorescent light. I seems they tried the RGB LED mix to make white light and that gave them a bad name for just the reason you posted. Mind you all white LEDs are composed of RGB LEDs or equivalent but the mixes are much better and colour controlled. I have tried to hand mix RGB LEDs inside many of these bulbs and it just isn't the same. One of the problems is that these bulbs have 7 or 9 Watts of WW, the same of CW LEDs but the RGB colours are only about 2W total each colour. They always look weak and sickly when you attempt to mix them for whites of any temperature. The RGBWW/CW strip I have above my kitchen cabinets and under my kitchen bar counter produce a beautiful white light about 3000K but the light is so smooth and soft to view anything under them. That may be the result of so many Watts and all indirect light off my white ceiling too. It is much preferred to the BR-40 potlamp fixtures I have and/or other bulbs I have around my Gathering room....same protocol.
