Logia awakening is a good counterpoint. It might be verse breaking. To that I would say perhaps the Admirals will all have CoC, but not necessarily AdCoC. Just like all Yonkou had AdCoC but not Awakening. This seems like the balance beween top tiers, where Oda might slightly favour Admiral fruits, while slightly favouring Yonkou haki, but both still being well rounded in all departments. Heck even top tiers that have Conq coating like Kaidou/Big Mom and Shanks, don't seem to operate at the same level when it comes to Haki (Shanks is a notch above).
This also wouldn't contradict Chinjao's words, Admirals not getting CoC would make Chinjao out to be a liar.

Notice that every conqueror haki showing post adcoc usage (kaidos first thunder bagua) was a user that can use adcoc, too
(Kaido, Oden, Garp, Zoro, Yamato, Gaban)
It also seems unlikely to me that oda will show just base coc because that would be like part 1, like marineford, which would be more of a character/personality moment thing, which we see with kizaru, is not needed. And part 2, Dressrosa, also is not something that is needed cause it purpouses with don chinjao and doffy was to show how common it was which is already etablished by now.
I want to add that, if you for example are right with your feelings and Kizaru and maybe even not Fujitora will not have full allout fights against any M3 members, or their final opponents, the chanche goes incredibly down imo, for example
