Agree, graphically it's fitting the atmosphere. The series is also brutal and full of gore. Just disappoiting in the lack of nudity and sexy babes though, Conan comics are full of those.
I'd say its because of conflict of interest why they had to dial down the sexual tones. While it's marketed for young adults, being animated means it will appeal to younger audience.
It's like Genndy Tartakovski's Primal. Being set in a prehistoric-era, it's a rather violent cartoon. But despite the cartoon being about primal needs of survival, well, there is sex in the show but it went kinda weird and obstructed.
