This reminds me of the party I had, at age 16, when my parents stupidly left me alone at our house for two weeks. It was a huge success, and there were bodies laying all over the domicile by AM's bright light of morning..
However... young TB (no relation to CB) decided to spill his drinks, and snacks (Cheetohs) all over mums carpet by way of hurling 'em out his gullet, in several areas of the living room.
On cleanup the next day - it was immediately evident that we could not clean only the spots - since the cleaner areas showed up (and our overactive Telltale Heart imaginations were going nuts). So, being good lads, TB and his friend JD cleaned the carpet in the entire house, by hand, on knees, with scrubrush and towels, while I repaired the thermostat that some crazed guest broke, while doing his imitation of a raving M'butu ritualistic dance.
I'm sincerely afraid, ol' bean, that you're going to have to feather that finish perfection (not imperfection) into the entire body, by buffing out the rest. When you micromesh or otherwise continue to rub on that area, its going to get thinner - and still not match - that satin or matt finish.
