Yes, in some European countries Apple doesn't have physical stores and relies on official partners for retail for physical stores. In some of these countries, you can still shop online on the official Apple store for that country. Major down side is you can't get Apple care at all.
The difference is my partner didn't buy her gadgets from a retailer. It was all from physical Samsung stores and under extended warranty. It sounds like an oversight on the retailers side that they didn't 'activate' your warranty for some reason.
But yeah, official stores and Apple Care not being available is a major downside, which is why I'm waiting until Im back to Canada to get an iPhone (it's also quite a bit cheaper on that side of the Atlantic).
One limitation I know of with Apple Care is that if you need to replace your device under warranty, they will need to mail it to you from the country of purchase, but you will get a temporary device while you wait for that. Samsung would never...
