Chapter 15: The Believer - S2-E7
Revealing mistake: The first time we see Imperial troops saluting Bill Burr and Mando from their POV inside the truck, they are using their left arm. A couple cuts later we see that the shot was flipped, since everyone on the bridge, both sides of the truck, is saluting with their right hand. (00:19:00)
Chosen answer: They could be just like wrinkles from age, like the elderly Togruta in the Zygerrian slaver arc in The Clone Wars series, as Ahsoka is considerably older than her animated appearances. I think there is probably a character design/stylisation aspect to it as well - the other Togruta we've seen in live action, Shaak Ti, has four segments or folds in her lekku that were not visible in her Clone Wars appearances, so it would seem the character design in Clone Wars and Rebels reduces such features.
