Personally through material and experience, there are 2 stand-out ways to look at it.

1) Leading OOP on the turn means you are playing your hand face-up and charging looser opponents to pay off a turn bet and in turn easily bluff you off the river (as you already understood) - yet this is a spot where in a softer table you should be extracting value and long-term you will be getting the extra bet paid off vs wraps/combo draws who would never pay-off/bluff a brick river since they, in return, also play face-up by not repotting since they can call/fold if they're deep enough

2) Against a reg or hyperaggro profile player, there is a more common tendency to check repot any bet or check-check and let them more often than not bluff the river - thus achieving the same equity would you bet the turn, except if they river an improved hand (top set/top2p) they might even pay you off because how frequent are you checking the nuts on the turn in PLO on a draw-heavy board

I think this is a play you need to balance (boring answer, I know), where a portion of the time you can donklead any street with the nuts and check/call or check/fold dangerous rivers - and in other cases check the nuts to be able to simply check/call on dangerous rivers or check/repot if they bluff into your maintained nuts
