How to tell whether I'm connected to Live or Demo server?

[[Deleted]]

I know you can see whether it's a demo or live server, as it's showing you, but it's just the name of the file. I could rename Demo file as Live, and it would show as Live. 

I believe some network of scam brokers they're using Demo account but claiming it's the real one, e.g.

$ strings config/SunCapital-Live.srv 
SunCapital-Live
Sun Capital Limited
173.234.164.170:443

So, is there any credible way of checking whether given server is a real Live, or fake Live, while I'm logged in?

Otherwise, why would broker want to blow my account?
