It’s not a meaningless distinction, as it cements it rather firmly in a broad era within a specific context of thought, unlike referring to it as a Goy library. If you refer to it as a Goy library, that both brings it within a Judeo-Christian context and completely loses all meaning. However referring to it as Pagan you now are more informed of the era and schools of thought employed at the time.
