What Iray properties to adjust to mimic polished leather?

Hi, everyone. Is there a document or video anywhere explaining what all the Iray properties do? I only really understand about half of them. But I applied one of the "smooth polished" "Aged Leather" shaders to this boot, and I understand this for sure. If I'd ever shown up in formation wearing these boots claiming they were "polished," I'd still be doing pushups! So what properties do I need to adjust to sharpen the shine?

I've tried playing with each property separately to figure out what it does, but now I'm only more confused than before. Any insight would be much appreciated. Thanks!
