An interesting question - but I don't think there'd be much of a correlation between whether you are dominant or submissive in real life and whether your dominant or submissive in terms of bondage. There's just so much variation there that I find it quite hard to believe there's a strong relationship.
I mean, I'm a fairly dominant person in real life, but when it comes to bondage, I'm nearly always a sub. But I've known other people (men and women) who are dominant in real life who prefer to be dominant in bondage scenarios. The same goes for submissive people. I'm obviously just going by my own personal experience here haha, but maybe there's some truth in it.
I'd also add that the whole sexual domination/submission is linked to how much power you have is a fairly outdated idea. Like most Freudian concepts, it's thought to be far too simplistic - reducing something that's actually very complex down to a direct causal relationship. Granted, it's the most well-known idea, but if you look a little deeper then you'll probably find far more relevant research which provides a far more wholistic (not to mention interesting) interpretation of the whole thing
