No, no, obviously I don't expect the valve to provide water outside of
the range of temperatures supplied to it. ?But some "thermostatic"
valves say they don't adjust for fluctuating supply temperature, just
supply pressure, e.g. some Deltas. ?That doesn't seem very
thermostatic to me.

I have seen ones with LCD readout you set the desired temperature too,
I was told they cost near a grand

Why are you going to all of this trouble as most taps are pressure
balanced and will keep within 2.2 degrees of set temp
