As an industry we are focused on bigness and greatness. But often it is the smallness that lets us down. To some it is laziness. When someone relies on "fix it in post" reeks of never really knowing what you wanted in the first place.
I love detail, and I love it when someone pays attention to them all. For example I love reading about how integral detail is to the Mad Men series.
the big rub is that detail, be it authenticity in the set of a commercial or anal attention to detail in visual effects, is lost on the greater audience. But those who care, care a lot, are are probably the ones who actually care about your product. It's kind of like 10 year old syndrome. Remember when you were 10, and whatever you were into, you were really really into. How many times did you read that comic book or magazine you were into. As adults, we lose a lot of that, but still retain one or two things in our lives still in that regard. For some it's golf, others NASCAR and others still fashion or home furnishings.
Though, while detail is most pertinent to your core audience, while they may not consciously recognize it, great detail, be it elegant design, typography or just beauty can still affect or still the broader population. While a bit of a tangent, this changing typography of highway signs is really interesting, given it's something we never think about, but use daily.
