So the real question is what temperature is the Thermostat? I would guess it is close to 190 degrees. Typically Gauges are within 10% Accuracy so it could easily be running at around 190 Degrees.
I would suggest that if you use an infrared thermometer you target the neck where the Thermostat is, the area where it discharges and the area where the Temperature Sending Unit is located. Write them all down so you can see what it is going on there.

Harbor Freight has a very reasonably priced infrared thermometer and they are having a sale right now;

I have used a probe in the radiator fluid--BUT YOU HAVE TO BE VERY CAREFUL NOT TO OPEN THE RADIATOR CAP WHEN THE RADIATOR IS HOT!
