same live dealer game pays different side bet odds depending on lobby

Been noticing something weird when I bounce between different lobbies lately. Exact same live dealer blackjack game, same side bets on the table, but the odds for stuff like Perfect Pairs or 21+3 are not matching up. Sometimes the payout is noticeably higher in one lobby than another, and there’s zero change in the rules or number of decks used. I always check the little rules info popup, so it’s not just memory playing tricks.

This really messes with tracking long term value if the odds shift just by which lobby I’m in. I like to chart everything and plan the week’s sessions in a Google sheet, so seeing fluctuating payouts throws my math way off. Curious if anyone else has tracked or compared this, and if there’s any rhyme or reason for the differences.
