I thought the same but I'm skeptical on this one too. Since the haki sparks appeared on impact in G5 against the snake on Elbaf, I have a theory that Oda was mostly drawing these on impactul panels and not throwaway panels where Luffy is failing to do much. Lucci fight is the only thing stopping me from fully believing it since he did land a big shot on Lucci at the end, but we didn't see the lines.
The next major battle will be the dealbreaker for sure on where base Luffy stands. Luffy has no reason to not use adCoC if he is struggling without it and the situation is dire, it makes no narrative sense.
