Which graphics APIs texture formats are HDR texture formats? I understand that HDR files are images encoded with a higher precision in order to keep more details.
When loading such images in real-time rendering applications using common Graphics APIs (DirectX, OpenGL, Vulkan), which are the "HDR texture formats" that ensure details will be preserved?
Also consider these alternatives for reducing bandwidth in comparison to R16G16B16A16.

DXGI_FORMAT_BC6H_UF16 is block compressed fp16 (half) RGB.

Common image file formats for HDR are exrs or dds. They're pretty trivially encoded as 32-bit or 16-bit per channel floats.
