UltraFlix and Apple Soon to take over the world of Live 4k sports entertainment...
Apple first added two categories in early November: Games and Entertainment. The additional categories (via iDownloadBlog) gained since include Education, Health & Fitness, Lifestyle, News, and Sports.

Apple highlights a collection of quality tvOS apps under each category. The education section, for instance, features the educational Noggin channel as well as the Star Walk Kids astronomy app and TED Talks. Health and fitness apps include Yoga Studio, 7 Minute TV Workout, and similar apps for exercising and getting fit. Other sections include a fair mix of apps previously available on Apple TVs and new apps totally new to the platform.

Viewing new App Store categories shouldn’t require a software update but may require a reboot.
