subject auxiliary inversion - The order of words in a clause: "tell me who is the real man" vs. "tell me who the real man is"

"Tell me who she is."

"Tell me who your boyfriend is."

We usually reverse the order, so it becomes like that.

But I wonder whether "tell me who is the real man" also works because "tell me who the real man is" sounds like we have already known the real man and I am just asking about his name.

If my friend and I are going to arm-wrestle, and I say:

"Let's see who is the real man."

Is that correct?
