My primary concern is for immersive VR media on our Go and Quest platforms, which use Snapdragon 821 and 835 SoC, respectively. The 821 doesn’t support 10 bit on anything, and the 835 only supports it on h265. Software decoding a 4k60 video on mobile isn’t an option, and you can see every bit transition with dark adapted eyes in a vr headset, so getting full 8 bit range is pretty valuable.
