The power factor at any point is determined by the supply voltage at that point and the current passing through that point.
The power factor of the lines and cables on the supply side do not affect the readings at that point.
The measured power factor only applies to the down stream connections from the point of measurement.
If the supply upstream of your connection is over corrected, it will not affect your metering at all, but it could cause the voltage to be higher than it should be. The other potential is that there ay be some resonance issues when the load is very low.
