I think I have the answer to this issue at least for the 40 inch n5200 model. I purchased this form Best Buy 2 days ago. I could not find the hulu app in the app store. After 4 hour of trouble shooting i went back to Best Buy and I discovered that the same model shipped in 2 different boxes.

I exchanged the TVs and the one in the box with the Hulu picture on the box comes with the app preinstalled.
