Was that Sanji's COO or HIs obsession for women at work? Zoro sensed alcohol from miles away when SH's entered Onigashima's territory. That must mean he too has a form of COO that's superior to anyone else in the world, right?
Sanji has these type of feats through out the time skip though, it's not a one time thing.
Zoro showed incredible sense of smell when it comes to alcohol because he was starved of it during his training, and it was a one time occurence not highlighted in multiple arcs.
It's obvious that women being involved helps Sanji focus his CoO more because of his interest in them, but that goes to show that the ability to pick up on those details is there, and is superior to the other SH's.
We can argue that it's a bit less refined in that sense and Sanji has yet to expand on it to the point where it universally works on that heightened level, but the basis is there, and with the attention that's consistently brought to it, and how it was contrasted with Luffy and Jimbe most recently, it's going to happen sooner rather than later.
I'd say Luffy's comments in this chapter at the very least serve as a strong indication of that being the case.
