My dash isn't nearly as shiny as yours appears to be. I've never put anything on it. I think that helps.
Angle of the sun has a lot to do with it as could the seating position, sunglasses, etc.
I've actually looked at mine closely and I knew about it before I purchased thanks to this forum, so it's not that I just haven't noticed it.
Just to be clear - I can see some reflection but it's not nearly as pronounced as the photos. And it's worse around the top of the center stack but again not nearly as bad as the photos and not enough for me to notice it in normal driving.
