Vertex colored sculpt to Blender, no color found

I would love to build a workflow streamlined for sculpts that don’t require retopo or UV’s exporting them directly from ZbrushCore or 3Dcoat to render , however Blender isn’t showing the vertex colors of anything I import.

I’ve exported my file from Zbrush as an STL - no vertex color
Export the STL from Meshlab to PLY - no vertex color either

Is there some kinda switch I need to flip to have Blender show the vertex coloring ? Because Meshlab shows it just fine.
