Led tint is always variable. There is no way to know until you buy one and see. Chances are it will be at least a little different though. It's like a box of chocolates, you never know what your gonna get.
Many of the old ones were blue or purple but occasionally a white one could be found. The new ones seem to be less blue or purple but put up next to a nice white one there is still a hint of blue or purple in most. That is my experience at least and I've looked at about 40-50 of them since they were released.
quite true with LEDs, you grab any two LED, whether it be SMT, high Flux, 3mm, 5mm, Luxeon, CREE or Seoul, hit it with 1-5ma and look at the die using a magnifying glass, there will always be blemishes of yellow here blue there to tell them apart. Occiasionally you'll find a pure white one [1 5mm out of a batch of 100] only to realize the perfect oddball was the first to burn out:shakehead
