About the target frequency response, "flat speaker in an acoustic treated room"…

So seems several target frequency response claimed they are simulating the "flat speaker in an acoustic treated room", like Harman target and Sonarworks target (seems a bit recessed high frequency and an octave lower low shelf).
So the problem is, there're several scenarios fit this claim, for instance:
  1. An calibrated Hi-Fi floorstanding speaker in a treated audiophile listening room (Harman target);
  2. In-wall far field monitors in a recording / mastering studio;
  3. Near field monitors in a recording / mastering studio (Sonarworks target);
  4. Wall mounted speakers in a large cinema-like film post-production studio.
So the room size / shape / furnishing etc. may affect the result. And the calibrated speakers can't be absolute flat. Of course we know they would share something in common (like 3kHz peak, high frequency roll-off etc.), but does this mean there is no absolute correct target frequency response?
