400mH isn't a sprint.
And her 400mH record is nowhere near the most impressive--yes there is a big gap back to 2nd, but the 100, 200, and 400 records have stood for an eternity. Even Privalova's 60m has lasted for 30 years.
If otoh you mean the most impressive set in "this era", I would observe that it is the ONLY one set in "this era"--but again, it's not a sprint.
But you're right, boring is not the right word: crushingly boring is more accurate. There is literally not one second of free mental time during which SML pops into my head, unlike other sprinters and WR-holders, and even 400mH athletes. There are plenty of ways to transit 200 or 400m that are faster than SML. What SHOULD be interesting about it is that it is SHE who is doing it--but, like Felix before her, I give it a big meh. She is eminently suburban in attitude, a total dud, not someone about whom anything appears actually interesting. Just a palette of beige, the expected suburban pablum.
Lame. Heck, even SCR is way more interesting, and she hasn't even gone to an OG yet. Kambundji is more interesting. Tarsis Orogot and Sani-Brown are even more interesting--and Sani-Brown has to be the finals guy with the absolute least visibility EVER!!
SML, who cares. I will be watching for Bol and Dos Santos in the 400mH, Tebogo in the 100 and 200, Gardiner in the 400, etc. EVEN CHRISTIAN COLEMAN IS MORE INTERESTING.
Next!
