Erik,
The KX3 and KX2 (and K3, K3S and K2) display the voltage AFTER the
reverse polarity protection diode. That is the actual operating voltage
of the transceiver.
The Shottky diode typically drops about 0.3 volts, so the internal
measurement will be about 0.3 volts lower than a voltage measurement
external to the transceiver.

When using the special VFO B display to show the supply voltage, both my KX3
and KX2 disagree with the rest of my equipment. The radios consistently are
0.2V - 0.4V lower than my inline meters and my Fluke when measured at my
RigRunner distribution block and at the end of a cable (e.g. if I disconnect my
PX3). I don’t see any way to calibrate this, is this expected?
