Summary: Apple is notorious for not supporting a new technology. So, there is no doubt that Apple TV 4 does not support 4K video content.
Apple is notorious for not supporting a new technology until they think it is mature and has enough traction to appeal to a broad user base. 4K, while definitely where the industry is going, does not have broad adoption because the price points are still too high and there is very little content to support it. So, there is no doubt that Apple TV 4 does not support 4K video content.
