Level 70 and level 100 Supreme Grade Blade?.. What makes Yoru better than Shodai Kitetsu when its CoA Hardened by its user?.. Nothing, we have seen the same Supreme Grade abilities of cutting from far away without any air Slash.. If anything it shows that Supreme Grade Blades are on the same level..
And what would the level of Enma when it's turned into a Black Supreme Grade Blade versus it's original level?.. We know for a fact that Enma will get more powerful as it will graduate from his Blade Grade, what makes Yoru better?.. It wasn't a Supreme Grade Blade before, it was a Great Grade Blade.. That's how it got more powerful..
Says who?.. Seems like you're limiting yourself and your imagination in a story where there are Dreams within Dreams..
There wouldn't be a higher classification of Graded Blades either if a Supreme Grade Blade has never been turned Black ever in the history of One Piece.. A Black Supreme Grade Blade is a Great Grade Blade turned into a Black Blade, it's just that simple..

There are no blades that can normally be stronger than SGs anyways, a Supreme Grade coincidentally being a black blade is such a rare occurrence. Only Mihawk has ever wielded a black SG, an isolated case for hundreds of years.
