I assume it is genuine, and I see no reason to believe otherwise. It is the trim that came with the steering wheel when I bought it—see the forum purchase link above. Based on the fitment alone—it sits perfectly on the wheel, and all the tabs engage exactly as they should—I am confident that it is genuine. It would be very unlikely for an aftermarket plastic piece to fit this precisely.
Since you asked, however, I have just removed it and photographed it from several angles so that you can get a complete picture of its condition.
The link contains the photos I just took, turning the trim toward the light so that the finish marks and minor signs of use are clearly visible. Once installed in the car, where it sits at a fixed angle, I doubt anyone would notice any of them. They are purely superficial imperfections in the finish, not actual scratches.
