so many obvious, checks.
does the torque pro show 200F on a 2nd car? the OBD2 does the math starting in 1996, (not like old OBD1 tools hand to do binary conversions those days are GONE)
the OBD2 tool only reads and presents in F (or C) what the ECU calculates this only the ECU does. and reports in real temperatures scales.,
if one car reads right 200f for 200 or 180f for 180F and your car is omg 60F degrees too high? that means WRONG, ECT sensor in car.
if both read wrong and too high the tool is crap, find another tool or if APP , another APP. (bad app ,or bad tool, what is easy to change for you IDK but all; shops have 2 tools, to make progress you must) or barrow one.
that is what Id do first, as the ECT never lies, unless it is a wrong sensor, or stuck in an air pocket and reads way way low or surges like mad.
once we know this, we can blame car or blame the tool.
reading coolant temps is not easy. (good IR guns do a good job but takes practice ., some are junk $10 tools are) try the top priced tool IR at harborfreight?
not saying your gun is cheap or wrong.

IS your ECT readings surging ? if yes , did you use the mandatory thermostat rubber slotted ring around the themostat edges, if not the stat floats and goes MAD, then you next.
do not use paper gasket if you see that 4mm lip in the stat base housing only FACTORY (or Gates) rubber surround rings work,
