Have you tried rotating the ship to see if the color shifts as lighting hits it from another angle? The example you give is mouse button #3. If you don't have that button on your mouse, map it to something else and rotate your ship.
At any rate, the artifact you are referring to I assume is this one I call out in the screengrab. To me that doesn't look like a bug but it looks more like a random shading error caused by the angle of how the ship is being displayed in the Store Function. If you rotate the ship and it changes and goes away, then you know that is the case. Either way, the representation in the Store is only an approximation of what it would look like in-game. The reason for this is that the ambient lighting in-scene will affect how your ship looks. The best example of this is to do a screengrab via external camera of your present after you enter a system for let's say a Class M red star and then compare that to what your ship looks like under a Class B Blue-White star. If you hold the two screengrabs side by side, it looks like the ships have almost two completely different paint jobs. This is also true in real life when let's say one parks a yellow car under sodium vapor street lights versus under white lights found in some retail parking lots. The color of the paint looks different their too.

Also note, your graphics card, monitor calibration, whether you have HDR enabled and a whole host of graphical settings can impact any video game color fidelity.
