What you create device you are passing an array of D3D_FEATURE_LEVEL values, when function succeeds the chosen feature level will be returned as through pFeatureLevel pointer. Returned feature level determines highest shader version supported by video adapter.

constexpr const ::std::array<::D3D_FEATURE_LEVEL, 4> feature_levels
{
    ::D3D_FEATURE_LEVEL_11_0
,   ::D3D_FEATURE_LEVEL_11_0
,   ::D3D_FEATURE_LEVEL_10_1
,   ::D3D_FEATURE_LEVEL_10
};
::ID3D11Device * naked_p_device{};
::D3D_FEATURE_LEVEL selected_feature_level{};
::ID3D11DeviceContext * naked_p_device_context{};
if
(
    SUCCEEDED
    (
        ::D3D11CreateDevice
        (
            p_adapter
        ,   D3D_DRIVER_TYPE_UNKNOWN
        ,   nullptr
        ,   creation_flags
        ,   feature_levels.data()
        ,   static_cast< ::UINT >(feature_levels.size())
        ,   D3D11_SDK_VERSION
        ,   ::std::addressof(naked_p_device)
        ,   ::std::addressof(selected_feature_level)
        ,   ::std::addressof(naked_p_device_context)
        )
    )
)
{
    // inspect selected_feature_level...
}
