That's because OpenGL implementations aren't guaranteed to produce
identical outputs when given identical inputs.
Graphical conformance tests would probably be

Well, no, not for d3d applications.

The OpenGL specification is not pixel exact. It therefore does not
guarantee an exact match between images produced by different GL
implementations.
That's from the OpenGL specification, Appendix A.
Also note that we wouldn't just be comparing different OpenGL
implementations with eachother, but

This was the approach I intended to take. I'd sum the squares of the
differences of each pixel, and check to see if the score is below some
threshold. With carefuly chosen tests and some trial-and-error, it
should be possible to determine conformance with reasonable accuracy.
