I’m sure Pelia had a flash of recognition, but she is not the same type of high and wise immortal as Guinan. 200 years is a long time, and perhaps her memory isn’t perfect. La’an didn’t tell her explicitly that she was from the future, so she might just be having some serious deja vu and wondering about the resemblance of this security officer to that weirdo who showed up at her door in 2022.
