Still looks more like when you sharpen too much to me to be anything other than noise. Now, I’ve seen some good grain like effects from the sony sensors being used by Oly & Fuji but I (personally) do not see it in this one.
Try something at that ISO but in lower light to get a slower shutter - that might give a better feel for grainish noise?
As an aside, I’d print that crop. 8x10 & hang it on the wall as a meditation.
