I suspect that's an answer only someone from Samsung would know.
For any of us to know for SURE, we would have had to have purchased every Samsung product and seen the packaging.
MY answer would be, if you've already got the product, and it's working as it should, then does it really matter whether or not it's a Samsung product?
That aside, keep doing what you're doing and reading the comments, and avoid the ones where folks are saying that it's not an authentic Samsung product.
