I still have some residual effects in the one ear, though it seems to be diminishing. Kind of a low ring, and a sproingy effect/noise if I rub the entrance to my ear. I am thinking it will go away.
It really does look like I had the tire change done properly, and in fact, the bead looked seated evenly around the rim, so if I had understood the proper pressure to use, I would have stopped there and been just fine.
Spudman, who I rode with in my other post above, and who has worked in bike shops a lot over the years, said this has happened to him and others in the shops, with higher pressure tires, and to accept the mistake and get over it. It could have been worse and I could have had the tire and wheel between my legs, or held in my hand, or something could have hit my face or eyes.
And to be clear, I LOVE my carbon rims and tubeless set up with a 2.5 Minion (DHF) in the front and have loved the 2.4 Ardent which is being replaced by the Minion DHR in the rear, and the lower pressures I can run as a result. That, and the dropper post and newer geometry of my Kona has really helped me improve confidence on both flat and banked corners on our sometimes dry and loose earth. Not saying I am fast, and that is not really my goal at this point. Confident, in control and flowy is more the goal for me. The tubeless has helped.
I don't plan on worrying about tubeless for my road bikes. Tubes work fine, and I don't pinch or flat there much anyway. In that world, if it ain't broken, I am not going to fix it. If I buy a new Kona gravel at some point, and it comes tubeless, I will run what it comes with on that bike. But I have some other financial priorities before I can get to that purchase.
