no, it's just a combination of the hair and the shape of his ear :D.. btw, i noticed some time already, he has something small and green tattoed (?) behind his left ear. You can see it here. I noticed that on some photoshoot as well.
This was in 2016, when he was just in one season of GOT and in narcos. Most ppl didnt know him back then. Hell, I didnt know of him til last of us lol.
