Please see: all of 4e. Specifically its Asmodeus's fault and the fact that wizards wanted to standardize Tieflings into roughly one type for 4e.
It's got a little better in 5e (especially since most people ignore the hard rules and just make whatever they want), but few dnd games in the past decade have had good Tiefling variety. We got colours and horns and that's about it.
