HEVC/h.265-encoded content not displaying in Computers > Movies

With the latest Handbrake code, I've been able to use h.265 to encode assets playable on macOS 10.13 beta. These same encodes can be added without issue to my iTunes library, but will not show up in Computers > Movies on Apple TV. Does anyone know if h.265 support has actually been added to tvOS 11 yet? I'm using beta 2.
