> On Android to switch the display mode, we use the `Display Mode API` which gives us the resolution and refresh rate of every mode that the device / display supports and that we can switch too. However it doesn’t tell us which of those modes support HDR10 or Dolby Vision etc…

What about the [`Display.HdrCapabilities`](https://developer.android.com/reference/android/view/Display.HdrCapabilities.html) API? Or will that only get you the capabilities of the active mode? If that is the case, how feasible would it be to cycle through a set of modes to figure out the capabilities of the display and cache them for future use?  
It’s not an elegant solution by any means, but could it be a potential workaround until there is proper support for querying the HDR capabilities of all supported modes?
