I've seen this said a couple times and I don't think it's true. I can't recall if they explicitly call it saidin but they definitely talk about the male side of the power and differentiate it from the female. They also have the Aes Sedai mention how terrifying it is to not be able to see Logars weaves when he's captive. They just know it's there because they're struggling to contain him.
The show is far from perfect but given there were only given 8 episodes, got hit really hard by pandemic shutdowns and then had to shoe horn in last minute plot changes due to Matt going awol (who I thought was the best of the boys, despite having to do the whole possessed by an evil dagger gig for half his screen time) I'm willing to give it a pass and see what they can do/clean up for season 2.
