Would be interesting as an experiment: send to the same recruiter a copy of your CV with a different picture and different name. Make sure you add a gender that it's not that common for the given invented name (e.g., invented name = Robert Langdon, invented gender = female). Keep the rest of your CV the same (perhaps shuffle it a bit, make non-core changes, change the font and layout). If the recruiter is moving forward with your application, then you have a pretty clear proof of discrimination (now, what's the reason for the discrimination? No idea, but it's based on the diff between your original CV and the modified one).
