No. I have watched Netflix, Hulu and Amazon Instant through a streaming Bluray player for over 5 years with no problems.
If your Smart TV has those apps, you should be able to watch them.
The wife and I bought this Firestick mainly for several apps it has that even the newest Bluray player, bought just this past Christmas, doesn't have.
Like Acorn, BBC stuff my wife loves, and a lot of it not available anywhere else.
