To my mind it's the other way around. A "loud" recording with little dynamics sounds OK at lower volume; the listening fatigue sets in when the volume is increased. A dynamic recording, on the other hand, often sounds great when you turn up the volume and can really hear the difference between soft and loud sounds.
