The Yamaha NS-10m, which dominated the studios in the 80’s was far from flat and analytical. In my experience, engineers and producers just wanted consistency between studios and the good ones could predict how the music would sound on a wide variety of speakers by extrapolating from what they heard on the Yamahas. Same thing with Auritone 4" cube monitors. Hugely popular.
As for concert sound, engineers are faced with a multitude of issues - feedback, monitoring projecting in huge stadiums and open air - not to mention budget. The Grateful Dead had a huge high-end sound system, but it proved too expensive to keep.
