Just to make this clear for people who don't already know OpenGL:
The public API state of OpenGL can be queried programmatically and with tooling such as Renderdoc, and it is of course standardized. The hidden state in drivers that you are talking about should only ("only") matter for performance, not correctness. Sometimes it matters for correctness when drivers are buggy, which many are. Driver quality varies widely, with mobile platform OpenGL drivers generally being the worst.
