A pedigree's and dog's value is all relative to who paid for it and what they want from that dog. Many people on this forum will tell you that you could've gotten something cheaper that would probably meet your goals. To tell you the truth, SchH3, IPO3, KKL1, is really not hard to find all throughout a pedigree if you find a good breeder and most of those pups in the United States are going for much less than what you paid.
The thing with pedigrees that I have learned is that unless you really really really know what you're looking for. You know what a certain dog produces and want that dog in the 3rd generation and another dog in the 2nd and another in the 4th ect. ect...you won't really get anything out of looking at a pedigree. When it comes to show lines...you're really paying for the prospect of winning shows and possibly sudding/breeding later on to make a little bit back (and the glory of telling your neighbor's your dog is from champion lines). It's an inflated price that is due to the market, not really the true value of a dog.
Value is very subjective. You have a great dog, from great parents, and you should be very happy with your purchase. You will find 100 people on this forum that will tell you that you could've gotten the same thing in America for cheaper/less. You paid a premium for a dog imported from Germany, maybe that comes with some benefits maybe it doesn't (again very subjective).
A good working line prospect can probably be imported from Germany for 1000-1500, which is what you would pay in America from any number of great breeders.
