I have Oryx White and I live in even deeper and dark cornwall. The Pearlescent White 'Oryx White' from I can gather is Pure White with a Pearlescent lacquer on top. or at least this is what you get when you buy the spray paint for Oryx White.
I have found Oryx White can be touched up on stone chips fairly easily with good results if you use Chipex or a similar touch up paint solution. The thing that marked Chipex out from normal touch up paint for me is the fact you have a blending solution which removes all excess paint blobs on top of the surface after you touch up a chip. This means the touch up is miniscule and the paint is only in the chipped area level with the surface of the paint. The only time you can see if a chip is touched up with Chipex is in very specific lighting conditions and viewing angles. About 90% of the time you do not see it, and when you do, you have look really hard for it.
I would advise getting a touch up paint solution or use smart repair rather than the shield system you are are looking at. Enjoy the new car.
I would get Oryx White again without hesitation
Hope this helps.
