That's a lovely piece of Pao Ferro. Two of my basses have it, and it has been very wear-resistant on my fretless. I was never sure if they had impregnated it with something, as the finish is really satin smooth, and about 10 years as my main bass, always with rounds, has barely imperceptible amounts of wear on the fingerboard.
As the manufacturer (U.S. Masters) ceased trading a few years ago, I can't even ask if the board was treated. Mine has black epoxy line markers with no front dots.
