Does texture MIP streaming work on ShaderGraph materials, and if so, how can we visualise this?

I’ve enabled MIP streaming as per the documentation and in this screenshot I’m testing a few objects to confirm the streaming is working. Green shows the objects where MIP streaming is saving memory.

But, for the crate object where the material uses a ShaderGraph shader, the green won’t show up.

Does MIP streaming work for sure with ShaderGraph materials? Is this just a case where the Rendering Debugger is unfinished and not showing ShaderGraph objects correctly?

Thanks!
