A counter argument I'd give is has anyone ever described a TV as being too harsh, as in they can't watch it for an hour without experiencing "fatigue" that causes them to need to stop. Of course with a TV this sounds ridiculous we just want the most life like picture possible so these measurements are a great way to accomplish that.
With headphones though while something may sound more accurate it might not be enjoyable to listen to. It can be too harsh to our ears and cause listening fatigue. While the Sennheiser HD800 are a great pair of headphones I find them very difficult to listen to on a neutral amp for long periods of time. The only way I could really enjoy them was to get a warmer tube amp. In the end I replaced them with the Audeze LCD-3 which I would argue are less accurate headphones but are far more enjoyable.
