Amaterasu's Release was introduced as Fire Release from day one. And Blaze Release was introduced as the thing that takes the black flames that Amaterasu produces and does much more with it. That should be a sign that Blaze is on a level above Fire where Amaterasu belongs. So I frankly want to understand why Amaterasu is Blaze.

Because Amaterasu uses the flames that are released through Blaze Release. And actually, it was Blaze Release: Kagutsuchi that was said to do much more with it, not Blaze Release alone. But since Sasuke used Kagutsuchi alone to manipulate the black flames, Blaze Release has to play a different part in the whole. And what could it do, other than manipulating the black flames? Correct: releasing them, because it's a release.
