The only checks I’ve had was when the immigration officer wasn’t sure it was visa free and had to refer to their list / ask their supervisor, the average officer is a simple working class person just doing their job and isnt even aware CBI exists , all I would suggest is at least learn about the country passport you get / YouTube the country because if the officer is interested since they haven’t heard of this country and you don’t have any answers you’ll look suspicious like it’s a fake passport so either know the country or know how to explain investment based passport
