That’s because you don’t know how to use it.
It will tell you if a system has a smooth frequency response in the room and if there are peaks and nodes (assuming a good recording).
Also, to do this, you need to go back and find the original direct transfer and that is what you are comparing the system too.
You are not listening to "what it sounds like" but rather "how close does it sound to the direct transfer" when listening on your quality monitoring system.
If you do comparisons in this manner, you will hear what the room sounds like as well as deviations in the system.
Sure, you loose imaging, soundstage, and the like, but you can tell trash from treasure.
