Of course, I could be talking total nonsense here, and it might be that
TRV systems have their lockshields fully open.

Some might suggest that, but I wouldn't. Unless you have a well-insulated
house and a massively over-spec'd boiler and rads, some rooms will heat up
at ten times the speed of others. I have been around my house tinkering
with the lockshield valves on all 14 (TRV-fitted) rads. One is wide open, a
couple of others about half-open and most of the rest are open at most 1
turn (there is one so-and-so that is just cracked but still gets plenty of
flow). Prior to this, the room with the now wide-open rad used to only
start to seriously warm up after an hour. Quite possibly the pipework to
that radiator could be improved, but that would be a big job.
