In today’s world of digital audio, sound can be tweaked pretty much any way you want it to be.
So it’s no longer the end of the world if measurements stray from textbook perfect.
As long as the speakers are up to the task of filling the room with sound up to desired SPL levels without distorting and the amp is up to the task of driving the speakers well, you are in a good place.
Maybe just have a handle on dispersion pattern of specific models in order to be well informed about what to expect there. This is one example of where measurements can help.
Toss in some proper DSP like that available in Roon software for example and the sonic details are yours to adjust however you see fit .
Having said that, good measurements are typically an indicator of good design and implementation and that is always good things to have working for you out of the gate.
