I created Gray8 and Gray16 WriteableBitmap grayscale gradient images, respectively, and they look the same on a 10-bit screen. All color maps to 8-bit depth.
I tried using D3DImage, but I still didn't get a grayscale map with a 10-bit depth display.
So, Does anyone have an example of WPF displaying a 10-bit grayscale map?

Since WPF uses Direct3D 9, only 8-bit output is supported. 10-bit is only available on Direct3D 10 hardware level. It is unclear to me whether newer hardware with older Direct3D would allow creating 10-bit output format, but either way the swap chain in WPF would need to be updated.

Me too. WPF probably won't change this issue. I'm looking for a way to render manually in DirectX or OpenGL.
