I got HDR at 4k60 now (but Dolby Vision still shows unsupported)
@Nilu334 bro you can also try this(if you haven't got any success yet)
Whenever I was changing to 4k60, color format was changing to 4.2.0 8-bit automatically which I never noticed.
HDR formats support 10-bit or above.
When I changed 10 bit or above in settings, it gave HDR at 4k60.
(Apple TV 4k box and other device has either settings for Adaptive or Auto change to Content's Dynamic Range and color format)
