This leads me to consider that the Radiator fan is running on low speed and the trigger temp seems to be around 96C.
This is a good example why knowing when the radiator fan is ON is useful.

That does seem correct. My turbodiesel's fan turns on at 98C and off when the temp drops below 90 or 91C.
The fan goes into 2nd stage, or high, if the coolant temp rises above 104C, iirc.
Ecodriving goal: Drive so efficiently that the engine does not waste enough energy to heat up to 96C.
