It's at least coming from some training and connects with previous story beats
It's at least coming from some training and connects with previous story beats, this is now headcanon territory but if we see CoO as the weakest part of his training followed by CoA and finally his supposed specialty being CoC then the accelerated timeframe on top of his Udon training to grasp haki concepts at least pays off in some way to his efforts so far, CoC was seemingly only useful for fodder control yet even powerful figures in Marineford feared it for some reason.
I see it as something abrupt but more understandable than his first gears, the idea of haki blooming from some epiphany has been somewhat present and the concept of some small connection with his understanding of haki and specialty with watching Kaido apply it first hand works for Luffy like it did with soru and Katakuri's vision.
