HDR Sample unsupported color space error

[simon-yeunglm]

Hi, when running the HDR Sample (https://github.com/microsoft/directx-graphics-samples/tree/master/Samples/Desktop/D3D12HDR), changing the back buffer format using the PgUp/PgDn key, the following error is displayed in MSVC debug output panel:

DXGI ERROR: IDXGISwapChain3::SetColorSpace1: Unsupported ColorSpace specified. [ MISCELLANEOUS ERROR #262: ]

But the output of the monitor seems working correctly for all 8/10/16bit back buffer format (correctly display SDR and HDR content).
This error occurs when changing back buffer format between 8bit <-> 16bit and 10bit <->16bit format, but with no error when changing between 8bit <-> 10bit.

Is it an issue with my computer set up?
I am using:

RTX 4080 (driver 565.90)
Windows 11 ver 23H2 (OS Build 22631.4602), "Use HDR" enabled in system display settings
Alienware AW3821DW monitor

Thank you
