Unless they ask you to, you tell them. And I think that by doing that and telling that you come from that background and maybe give them a bit of display how you have learned everything by yourself(Great quality!!!), you mind end up even with more respect.

But I would only talk about it if I had to. When I go to interviews, even though that I have a BS in CS, I don't talk about it, it's already on my CV and people should know it. As I'm a Senior/Lead whatever developer with many years of experience, that makes no difference whatsoever. Because even my deep knowledge I've learned in CS about B-tree algorithms already has been mostly forgotten and can be revived only by Googling it a few minutes, and if I'm preparing for a interview, I'll review it... and those things are better proven live(in a whiteboard or in a coding challenge) than with a Diploma(which very rarely they will ask).
