The white gene does not produce paler colors. Think of a white dog as a GSD of any GSD color and pattern that has had a white sheet dropped over it, mostly hiding the dog's color and pattern. The white gene successfully hides the dog's black coat coloration from view.
However, the white gene does not totally hide the red/tan/cream/silver coloration from view, and when a white dog is genetically red or tan, the result is that the white dog's coat color is off-white in degrees ranging from only slightly off white or cream colored all the way to having strong shades of tan or orange in the coat,
White dogs who have the whitest coats are genetically creams or silvers, not tans or reds. In breeding whites, if one selects for the whitest coated dogs, one also inadvertently also is selecting dogs who are genetically creams or silvers.
A white dog must be bred to a colored dog whose color and pattern genetics are known and who is not a pure for agouti/sable because if the colored parent is pure for agouti/sable, the resulting progeny will be all agouti/sable no matter what the white dog's hidden color and pattern is. If you breed a white and a black and get agouti/sables or black and tans for example, then you know the white parent's hidden color and pattern genetics since the solid black can only produce black, . If you breed black to white and get a sizeable number of black pups in the litter and no other colors or patterns, then its most likely the white dog is genetically a solid black although getting the same results in more than one litter provides more substantial proof.
There are many dogs who are silvers or creams that do not carry the white recessive. And if you would breed a white dog who is an off white color, especially one with hints of orange in its coat, to a black and silver, you will get rich reds and tans and you would only get cream or silver if the white parent carries the genes for cream or silver.

No they are not "rare" or desirable, it's a washed out black/tan. Most breeders try to breed for the deeper richer pigmented dogs.
