Zoro himself doesn't know he has CoC and he can't use even the basic of it. Him getting advanced CoC when Luffy just got it and he could fully controll his CoC after the TS and it got stronger after each fight, makes absolutely no sense. That Luffy got it is already questionable enough.
Kaidou said Kid has CoC just as Luffy. The question is if he can controll it to the extend like Luffy could after the TS or not. If he can, he might get it this Arc - Oda just throws Haki PU's left and right recently, but if he can't then no.
