It's not about being told how to sound, more a question of taking sufficient interest in how you sound, in the context of the music, to make a positive contribution to the whole. It matters, and out-of-context sounds (which includes poor quality in a generally high-quality setting) get noticed, as will those responsible for them.
Yes, thats ok.
But we all have a different idea on how "to make a positive contribution to the whole".
You think a member of the audience dictates, more or less, what is a good bass sound and you should take care about that.
I think you are the professional and your job is to offer the best sound based on your criteria since the opinions are subjetive.
