UglyGenius I think addresses it best.
Okay to say you have ADA 100%. The equipment, substrate, filter, and light all have to match. But my main question is what is the purpose of all of this. You want to create a stunning planted tank and all that rivals that of Amano. Is that not possible with anything not labelled ADA. If someone had a ADA clone with cloned equipment(to match the quality and workmanship) but the aquascape is identical, is someone really going to notice the difference. I mean is the person going to notice the tank is not ADA and say no man that is not an ADA tank, what are you trying to do.
On a unrelated topic, RyeGuy actually is a private seller of plants in my City, the beauty of his plants and aquascape rival those that one would normally see in a ADA tank. And he uses fluorite, Lol. And to boot, I have just recently started purchasing plants from him and I have yet to come across plants that were as healthy and algae free as his.
