It's fine to claim it. It's shorthand for "We achieve smaller FID values (most of the time) than any other generative model."
You're correct about what you're saying, though. It's also worse: FID is a measurement biased towards imagenet-style images, and this model was also trained on imagenet, so it's quite well-suited for achieving small FID values. Whereas for generative anime, it's still unclear what the best model architecture is.
