Bought a house last June, a two-story brick colonial with a gas
furnace and AC.
The supply in the master bedroom on the second floor is really weak.
Had a guy come out from a furnace/AC place I've been happy with so
far. He said the only way to really find the problem directly would
be to start ripping up walls, which isn't worth the expense.
Does anyone in the home HVAC industry ever use a fiberscope/borescope
for this kind of thing? (To inspect the ductwork for obstructions.)
TIA,

There is a whole lot easier faster cheaper way. Look at what size the
pipe is going to that room. Do and estimation of how many feet of pipe
and elbows are hidden in the floor and walls. Do a friction loss and
figure up how many equivalent feet of pipe you have on that run.
There's your answer. An improperly sized run.
C'mon, whad you really expect? Some giant size dust ball just happened
to be clogging the run?........maybe a nerfball fell down the pipe or
some dead gerbil?

That's a reasonable hypothesis, but every other supply on that floor
is pretty strong.
The pipe to the weak one is longer than the one to the bathroom, but
not nearly enough to explain the difference.
