Remember what I was saying in one of these threads about psychoacoustics not being a part of electrical engineering? I'm pretty sure it isn't taught in astrophysics school either. Here's their entire one sentence curriculum on the topic: "There's no air in outer space, hence no sound... The end."
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".
