An oiled braid... wouldn’t that create a grease spot if this were an actual area of contact?

Yes... the mostly undone queue that runs down the back of the neck and onto the shoulders of the image on the Man on the Shroud is slightly blurred compared to other image areas and hair images, probably because of the oils exuding from the queue onto the cloth. Any oil that was there has long since evaporated.

Note the slightly grayish area in the neck and down the back... the queue braid blurry probably because of oil or grease.
