Which is an important distinction, because sometimes the show-runners do decide that. In example of one where I think it improves it, in Youjo Senki, the military uniforms in the anime are... uniform, male and female. While in the manga, while not fanservicey, the female uniforms are clearly cut differently than the male ones and follow the bodyform rather than being blocky.
I vaguely recall an episode where Frieren met one of the few last elves alive, a male, and didn't bother trying to save her people by making children.
I remember that chapter as well, the reason being is that the Elf Dude was a Monk.
The show runners have clearly made it a priority to avoid sexualizing Frieren. She’s an asexual autistic blank slate that anyone can project on to.
Probably the manga-runners made that decision.

That is why Ubel was created, to be the sexually charged mage to fulfill that quota.
