How I interpret this is....hardening + barrier is the visual indicator for ID + CoC.
When you don't see hardening hardening around Luffy's limbs, he is simply using the barrier.
If you follow that panel, Luffy is only defending (aka he only needs to use the barrier not ID) from Kaidou's attack, Kaidou is being stopped by Luffy's barrier, Kaidou is not using one himself.
When Luffy follows up with an attack you see his hands are coated, which may imply ID is being used along with CoC. Barrier is mostly useful for defending anyway. In many cases you are stunting your attack by using a barrier, only ID is a true enhancement offensively for brawlers.

So you are saying BM has level 3 coa but Kaido who is superior in every way doesn't? Nah
