You could supply a helper application that you can launch and get the errors
from, if you can determine what operations are causing them.

You mentioned three options ("desktop", "angle" and "software"), but only of
two tests. I thought ANGLE had the best support, because it avoided the buggy
OpenGL drivers and instead used the translation layer to get to DirectX.

I don't write Windows software anymore, haven't for many years. Honestly didn't think anyone actually did anymore. Here's the concept one would use for package installed software.

Debian has a postinst step. RPM has %post in your .spec file. Depending on the tool you use, Windows should have something similar. I seem to remember Install Shield did back in the day.

Write three tiny test programs that tag along with your product. Create a batch/script that launches these three tiny test programs WITH KNOWN PROCESS NAMES. Have it launch, sleep for 3 seconds, then see which one(s) are still alive. Write that to an INI/config/whatever file and make that the first thing you look at as your app starts up to set the backend.

Leave the postinst script and test executables lying around. If they 
upgrade/change video cards the current working backend may no longer work.
