The higher fuel present in the oil is unburned, so I don't think it reflects piston ring wear - as stated before that's characteristic of cold weather idling where a rich mixture is present, gets past the low friction piston rings, and did not have the chance to get burned off or removed via the PCV system.
If your TBN were low it would be recipe for sludge formation. Since it's not it probably reflects a temporary condition that existed the day you changed your oil. A fully warmed up highway run would reduce the reading if the fuel management system was working right and your thermostat was controlling coolant temperature properly.
