The King and Queen can call elections. It is actually a real job. I am sure the calling of elections could be done some other way, but until that way is determined the Queen is a real thing.

True. But - in reality - the Queen will only do something that Parliament would approve of. So while she has all these powers, she is quite constrained in their actual use.
For example, the Queen can dismiss a Prime Minister. But should she dismiss one who has great support in Parliament, there’d be hell to pay. In fact it could mean the end of the monarchy.
So as I see it, the Queen is pretty much a rubber-stamping figurehead. And that’s not necessarily a bad thing. Because she is also a check against a someone like Hitler rising to power in the UK.
