The third piece of official art provided for reference, of Captain Xendros from 5E's rendition of Ghosts of Saltmarsh, does not have browhorns. But I'd like to see some browhorn options, too. My main thing right now though is not having all the horns look like they're carved out of volcanic rock and having some canon solid/near solid eyes available.
I'd also like a fro option that's longer than like someone's just shaved to go full natural a few months ago. But that's a big ask in any game it seems, and only tiefling-specific in the greediest of ways. (My tiefling lightning sorceress from one campaign has a pretty damn full one.) BG3 does already have some other curly hair options though and that in itself is just so refreshing.
