I'd imagine if they were to eventually launch on streaming devices, Apple TV would likely be the main one of interest. In the same way Sky have made Sky Go available on the ATV, its closed platform would mean its way more difficult for anyone to read the app's code and extract the streaming URLs. Any Android TV based platform would be unappealing. If Amazon are really moving away from FireOS on their future firesticks to VegaOS, maybe this will make them more confident in making the app available on those devices.

You don't need to extract the apps for the URLs. All you need to do is install a new Root Certificate on the Apple TV, which is officially supported by Apple for development purposes. You then can pull the URLs from a packet capture.
