[Question] 10bpp/HDR support

Reading from [Using DirectX with high dynamic range Displays and Advanced Color](https://docs.microsoft.com/en-us/windows/win32/direct3darticles/high-dynamic-range):

> Ever since Direct3D 9, graphics engines have been able to internally render their scenes with this level of physically accurate fidelity.
> ...
> When advanced color is enabled, the DWM performs an explicit color conversion from the app visual content's colorspace to a canonical composition color space, which is scRGB. Windows then color-converts the composed framebuffer content to the display's native color space. In this way, traditional sRGB content automatically gets color-accurate behavior, while advanced color-aware apps can take advantage of the full color capabilities of the display.

These lines want me to believe that using scRGB colors and `BitmapSource`s of formats like `Gray32Float` and `Rgba128Float` will automatically take advantage of any WCG/HDR display. However, later in the documentation it also describes setting up a swap chain to enable such output.

Can you please clarify whether the scRGB output is supported and enabled out of the box, or whether there are extra steps needed?
