Isn't DX 11 the same as OpenGL 1.1 whereas DX12 is OpenGL 1.2?

Edit, I might be mixing up OpenCL 1.1/1.2

DX11 is like modern OpenGL, DX12 like Vulkan.

(OpenGL 1.x/2.x is ancient, and comparable to DX8/9. All still used by old software, though.)

I still recall oh so many OpenGL apps failed to start when OpenGL 2.0 was released, as 1.x had been around for so long "everyone" had gotten used to just checking the minor version number.
