Suikoden V seam on a character model upscaled

[jekyjeky]

Hello, I've been playing around with the settings of the increased resolution with the game Suikoden V. However, I noticed that a particular character (Josephine) has a seam. I think this is just minor but it's bugging me every time I see her close up. It's like she's been cut in half with the seam going across her vertically. Could this be a result of the upscaling/filtering or do you think this is an issue on the game by default (perhaps not noticeable because of the low-resolution on the PS2?)

I've attached a screenshot with different angles. Please judge.
