I bought my 4K TV at the end of 2015 and there were no 4K media players worth buying then, hence why it's only now two years later that I'm watching 4K content on it for the first time. While waiting I used a Chromecast for Smart TV functions. I could have upgraded to the Chromecast Ultra at a later stage but 4K/30Hz wasn't future proof enough and no Amazon app is on the horizon.
Yupp. 8K is 5 if not 10 years away, and 4K/60Hz hasn't reached mass adoption. The 4K ATV will be future proof for several years.
Dolby Atmos is also on the way which I hope will improve improve sound quality. Last night I watched Wonder Woman and whilst image quality was excellent clarity, object detail and punch was noticeably below Bluray. It wasn't bad, just ok. I certainly didn't think in my head "This is so good I never have to go to cinema" Hopefully Dolby Atmos will enjoy higher pirate sound than DDP.
Meanwhile when I watch Oblivion on Blu-ray the sound completely takes over the room and elevates the heart rate. Pop "Les Miserable In Concert 25th Anniversary" into the disc drive and the voices of all the actors and singers are so clear it's as if I'm watching it live.
Hopefully with software updates, ATV 4K can give me the same escapism and sensory experience..
