I don't understand what you mean, sorry.
In many of the surround sound modes, which you can step through with the Program up/down toggle bar on the front panel, at least on my similar RX-V375, the center speaker light on the front panel display does not illuminate because it is not used in those modes. Are you perhaps using a mode that doesn't output a signal to the center speaker?
In A/V reproduction accuracy, there IS no concept of "accounting for personal taste/preference". As art consumers we don't "pick" the level of bass, nor the tint/brightness of a scene's sky, any more than we pick the ending of a novel or Mona Lisa's type of smile. "High fidelity" means "high truthfulness", faithful to the original artist's intent: an unmodified, neutral, accurate copy of the original master, ideally being exact and with no discernable alterations, aka "transparency".
