Gear S2 Updates (CPB7/CPC5) - Still Rolling Out?

I have the classic non-4g version of the Gear S2 (SM-R732) and I'm still on R732XXU2BPA4. I have been seeing news and posts about updates (R732XXU2CPB7 and R732XXU2CPC5) for the past month, but still have yet to receive either update. I chatted with Samsung and they told me my serial is invalid (despite buying the watch directly from them). So I'm curious, is there something wrong with my watch or have these updates not rolled out to everyone yet?
