I feel like there’s too many poly relationship structures to be able to generalise them all like that.
There’s plenty of people who have open relationships, where two people have a very close relationship (sometimes married) but they aren’t sexually exclusive with each other.
I’d also wager that some poly relationship structures would be more stable for lgbt people rather than heterosexual people, solely on the idea that everyone could participate more equally.
