If WSG isn't advCoC then Luffy wasn't using advCoC against Kaidou. There's nothing missing visually or narratively.
In that arc, we were repeatedly told they're using advanced Conqueror's.
Now, it's all guess game.
Blame Loda, not me. It's something I've said the entire arc, the visuals suck!
Even Morj made a video about it, about us having to create headcanon to deduce, that there is no definitive way to say them apart visually
