Original posting looks a bit spammy to me.... (virtually identical posting on heaps of forums, with same website link, and never any followup when people reply.)
Shame, as I only know this because I am looking for the same info, and Google keeps finding the same question above on heaps of forums!
It would appear there are several types of SK6812 available. I suspect the RGB stuff just works with standard WS2812 code.... however I bought the four channel RGBW version of SK6812! Really looking forward to working out how to control it with my Oaks (when they arrive soon!). Seems they just use a 32bit stream per pixel instead of 24bit for RGB version.
Hopefully there will be some code out there to use... or failing that something I can tweak to make work.... surely can't be too difficult to add an extra channel into the mix!
If my plan works, I'll be able to control two RGBW strips from each Oak (with a level shifter shield).
