Means much more with some details as to what sort of machine it was done on.
AFAIK the ceramic inserts are deliberately "not sharp", and the shiny finish comes from the burnishing action as the material is "pushed off" the surface, and not really "cut". But that takes power and rigidity not found with the machines that most here use. You presumably are using such a machine if you were hard turning a bearing race.
I don't think "cutting" ever really gives that polish, there has to be a "rubbing" element to the "cut".
But to be perfectly frank, what I see is a high polish on what is a somewhat irregular cut, based on the reflections in the picture shown in post 15. The polish may be causing the reflections to be more distinct, however, I cannot judge the absolute size of the irregularities from the reflection, and they may be small.
Keep eye on ball.
