4k 30Hz vs 4k 60Hz on Xi6 Portal

[anothermike]

Hello,

 I've noticed that if I set my portal to 4k 30Hz it outputs 10-bit 4:4:4 color, which is fantastic as I get Netflix and youtube HDR. However, if I set to 4k 60Hz it drops to 8-bit 4:2:0. HDMI 2.0 has enough bandwidth for 10-bit 4:2;2. Any ideas on why the Xi6 goes to 8-bit?

Thanks

Correction - if I set to 4k 60Hz it drops to 8-bit 4:2:2.

@anothermike it may be an HDMI, device or TV limitation when it goes to 60Hz. The Xi6 should be able to support up to 10-bit colour space.
