That's a weird assumption. I have literally done hundreds of gigs with dozens of acts. I get hired over and over because how how easily I tune into what's going on around me.
I'm also a sound guy. I started sending the board a brighter signal after trying to mix bands with horribly muddy bass tones. Plus, I use my technique to round out my sound as needed. I have leave all of my settings the same and make my one bass sound like half a dozen different instruments. If I use a pick near the bridge, and then pluck with the side of my thumb over the end of the fretboard, you get to completely different tones. And there are several degrees in between.
My tone has exactly zero to do with how well I "understand the band". Someone you respect must have steered you in a weird direction with that odd theory. They have nothing to do with each other.
And, according to the people who keep calling me for gigs, my tone is exactly what it needs to be.
What an odd line of reasoning....
