Creating a Headless context on windows is done via EGL. Per default GlRequest::Latest is set as context attribute. On my system (HD 5770 with latest drivers) the eglBindAPI( EGL_OPENGL_API) fails, which looks like a driver bug as the EGL 1.4 is supported. Instead of creating a OpenGL 4.5 context via WGL, the EGL implementations falls back to an OpenGL ES 3.1 context.

For example the gpgpu example of glium doesn't work due to this issue.
