RVT material more expensive then regular layered and lerped material???

I thought the whole point of a RVT is that it is cheaper then a layered and lerp and otherwise expensive instruction count material.

From the shader complexity view mode in 5.4 it is showing me otherwise. Anyone know why?

First image is the contributing meshes that get hidden in green… and 2nd image is the final large scale RVT nanite mesh.
