Unsupported TVs will need to have a supported external streaming device to access the Apple TV app on TV, either through a Apple TV box or a supported third party streaming device.

If the app is supposed to be supported, but not pre-installed, then it may be downloadable as an add-on app from Samsung’s app repository. Apps on your Samsung smart TV - Samsung Support
