Is there really no way for me to watch UV on my TV?

(I'm in Canada, so Vudu isn't available)

I bought Batman v Superman on UHD to future-proof my blu-ray collection (I don't have a UHD player yet) thinking that I could watch the theatrical release on the regular BD and then use the UV code to watch the extended cut in the meantime. I was planning on using CinemaNow on the PS3 since it'd be my first time using UV and I remembered seeing the app on the console a while back, but it turns out that CinemaNow isn't available anymore on it (go figure).

My TV isn't a smart TV, and I also have a PS4 and 4th gen Apple TV. I tried AirPlaying from the computer, but the quality is unbearable (if it doesn't refuse to play or crash).

Are there any ways I can watch UV on my home theatre without having to buy a Roku? I've been looking into it all evening and it's left me wholly disappointed...
