Some contents of 4K and Dolby Atmos are not working poperly.
Some contents of 4K and Dolby Atmos are played as HD and 5.1 Channels, for example, Black Hawk Down, Men in Black 1, Men in Black 3, etc.
In Detail page, those contents(Black Hawk Down, Men in Black 1, Men in Black 3) supports 4K and Dolby Atmos, however actual resolution and sound are not supported.
But, some contents works fine like Men in Black 2 or Men in Black 4(MIB international).
Regarding this, I made a Movie clip on YouTube with detail information.
