Does this matter in the scheme of things? Tried scrubbing with a rougher sponge but nothing. Caused by burnt LME.

not even a tiny bit
That’s called character. It makes your kettle unique.
No it really makes no difference but, if it makes you feel better make a semi strong solution of PBW and water ( assuming this is not a aluminum pot). Soak your kettle for a day or two and then take a scrubby pad like a scotch brite pad and scrub it should come off. I had something similar happen to my thermometer heat shield when I had a boil over and the method I described above took 95% of it all off.
It’s stainless FWIW

Can’t imagine it matters. I rarely brew using the outside of the kettle anyway :o.
If PBW doesn’t do it, I’d suggest Barkeepers Friend. I use it on my kettle and it takes everything off.
When brewing 10 gallons finished in a 15 gallon keggle it’s not a matter of if but when you have the mother of all boil overs. Doing this repeatedly leads to serious carbon deposits on the outside. Once in a while I take a while wheel to it. For the rest, indeed it’s character, or rather, patina. 8)
