As of Gen 8, official games do not. I Iron Headed a Carbink just yesterday with my Excadrill (4x weakness to Steel), and still only got the standard "super effective". Though I love the idea of differentiating text for 1/4 and 4x matchups.
As for fan-makes there are too many for the average person to test, and they're forbidden from discussion here anyway.
I'm not sure what you mean by a "WIP" answer, but I hope I helped. If not, let me know specifically what you're trying to cover and I'll see if I can edit.
