Black Sapphire Color Differences on Two Front Wheel Panels?

[mikey777]

Been meaning to ask all you good people here on X5World about this but my 2008 X5 3.0 in Sapphire Black when looking at the front of the car under bright sunlight, I see a difference in the shade of black from the hood versus the two body panels over the front tire area. It's not noticeable unless under direct sunlight and it's very faint. And it looks like the rest of the car matches the hood. Just the two front side panels are a different shade of black. Is it just my car or have others noticed this subtle shade of sapphire color difference?
