I'm pretty new to octane and I have a few questions about black materials.
I'm currently creating product assets for a new product we're about to sell which consists of a pretty black material.
Check out the real life sample (bad quality ahead):

I've recreated this as a glossy material with little roughness and some noise in the bump channel. It looks okay,
but turns grey really fast. Have a look (I unfortunately can't share the whole image or a scene file).

About the scene:
I use a backdrop which is invisible to the camera with a light grey material and a pretty basic three point lighting.
Rendering with Pathtracing.
What I'm looking for are some tips to get a more realistic black material as in the sample above.
Any tips for someone pretty new to octane?
Thank you in advance!
