I just got the exact same part for my car and kinda have the exact same complaint. The photo of what you thought it would look like is also the photo that prompted me to order the part.

I think it may be down to the material. The part you and I both got is kind of a soft-touch matte material unlike anything else in the car. The second photo you posted looks more glossy and a closer match for what's in the car.

I don't know if the two parts are in fact different or if it's just down to the photo, but I'm also a bit disappointed with the way the part doesn't exactly match its surroundings.

Let me know if you find out more.
