Never heard about this.
The Adafuit PDF Datasheet
says 6-7V (instead of 5!!!)
but this one
but they are different chips so your're right for WS2812B, the first one is WS2812 without B.
WS2812 has four pins instead WS2812B has six pins so you can distinguish them. I believe that I have only WS2812B but I have to check.
I like very much these LEDs!
