Haki is a power that comes from will power and spirit. In wano, it's called ryuo. There are three types of haki (CoO, CoA and CoC) or one can say haki gives you three types of abilities. As one becomes proficient in any type of haki, ability given by that type of haki will also become advanced.
For example, Katakuri has Future sight, after being proficient in observation haki.
As both, advanced and basic abilities comes from same source, that is will power, they all are generally referred as haki/Ryuo
Now, let's talk about basic and advanced usage of CoA.(please read panels carefully). I will be explaining the concept through Luffy and Zoro.
Basic color of Armament gives you ability to hit logia and coat your body part with armament /koka.
In wano, Luffy called koka, coating of body with armament, a basic ability and showed desire to learn advanced ability(deflection/Shockwave ) as shown by Rayleigh.
Hyo after noticing what Luffy is trying to learn (advanced CoA:deflection) says that in wano they have a similar ability through which a swordsman can cut anything yet nothing(panel is given above) -that is he can cut steel if he desires or will not cut even a paper, if he doesn't desire.
He went on to demonstrate this ability by deflecting a gifter.
So advanced usage of CoA = defection/Shockwave and ability to cut anything yet nothing.
Now, let's move on to more interesting part.
Zoro indeed has unlocked ability to cut anything yet nothing in alabasta as he was taught by kuina father who apparently belongs to Wano and so is Zoro who is shimotsuki. He did so under extreme situation but just didn't realize it to have full grasp until TS where Mihawk taught him how to make blade black.
Another definitive proof of both Zoro and Luffy having advanced usage of CoA is explain below
Now, the last part - highly advanced usage of Armament or as some called penetration.
Hyo mentioned that there is much more advanced version of CoA which allows user to damage object from within after Luffy broke the collar without making it explode.
So yes, what Luffy end up learning is much more advanced version of CoA.
However, for a swordsman this ability seem to be in parallel with making blade black which Zoro has yet to do and for that he needs to become one with the sword.
Which Mihawk taught him but he is yet to do so
The black blade has been equated to breaking objects from within on the basis of inference drawn from the above panels.
Learning the flow of haki gives ability to cut anything yet nothing and ability of defection.
As Luffy practiced this, he instead of deflection, end up destroying collar from within. One can imply, that he infused his Haki into the collar, altered it properties to destroy it from within(penetration and destruction)
However, the same concept is inherent in making blade black. Through consistent use of flow of haki into blades through countless battles, the nature of the blade will permanently change making it harder and black.(penetration and modification)
So both breaking collar and making blade black is based on similar concept of flowing haki and changing nature of the object from within permanently, with difference lying in that former breaks it from within and other strengthens it from within. Thus both being placed as highly advanced usage of CoA.
So in short,
Basic CoA(Hitting Logia, coating/koka) - - - - >advanced CoA [deflection/shockwave; ability to cut anything yet nothing ; haki imbued slashes (it's also based on flow of haki into slashes from user)] - - - - - - >highly advanced usage of CoA (destroying objects from within and making blade black)
If you have any argument against this, please substantiate it with facts and not your headcannon. Lol

Luffy calling koka - basic
In panel below, Luffy calls deflection advanced
In panel below, Hyo said that deflection ability Luffy is trying to learn is similar to ability to cut anything yet nothing.

This panel shows Zoro sensing the breathe of non living things and mention ability to cut anything yet nothing.
The panel below shows that Zoro dodged all falling stones as if he knew where they will fall(he was feeling the breathe of stones)
The panel below shows that Zoro even figured out under which stone his sword is buried.
And, in the panel below he demonstrated ability to cut anything yet nothing - he didn't cut leaves because he didn't desire but cut the stone because he desired. His swords understood his will. (similar to what Hyo said)

As I said earlier, hyuo was teaching Luffy advanced usage of ryuo/haki - that is focusing on making haki flow.
In above panel, notice Luffy's hand - it is surrounded by clouds. Now where we saw similar phenomenon recently
Did you guys notice the similar clouds around Zoro? But what's interesting is Zoro immediately tamed enma implying his control over flow of haki (the concept on which Hyo was teaching Luffy advanced version). He did so because he already been taught such ability, first by kuina father and then during TS by Mihawk.
