DXVK 2.1 Released with HDR Support, Shader Compilation Improvements
The biggest new feature in the DXVK 2.1 release is HDR support. HDR can be enabled for games on systems supporting HDR10 color spaces by setting the DXVK_HDR=1 environment variable or by setting the dxgi.enableHDR = True option in DXVK’s configuration file.
However, as no major Linux desktop environment currently supports HDR, users need a Gamescope session with the --hdr-enabled option enabled. Also, HDR support is only supported with the open-source AMDGPU graphics driver and some kernel patches from the Josh Ashton‘s branch.

Wine Reviews : DXVK version 2.1 has been released with HDR support
On systems supporting HDR10 color spaces, HDR can now be enabled by setting the environment variable DXVK_HDR=1, or by setting the option dxgi.enableHDR = True in the configuration file. When using vkd3d-proton 2.8 or newer, this will allow D3D12 games to detect and use the HDR10 color space if they support it.
