While it's true that humans can perceive up to 144db of dynamic range and 16 bit audio can only provide up to 120db while 24 bit can produce up to 144db, the fact is that the even some of the best recordings available only have around 96db of dynamic range. Unless the track has unbelievably good dynamics and you're listening in a perfect environment, usually with around 50 decibels or more of noise cancellation, you won't be able to tell a difference.
24bit for recording is perfect as it provides enough headroom and has universal compatibility unlike 32bit, which has an extremely large footprint along with being seldom supported by audio interfaces, but unless you're listening to a very badly encoded file, 24bit audio is basically pointless for playback. "Hi-res audio" is nothing more than a money making scheme by labels and distributors, headphone manufacturers, audiophile amp/DAC peddlers, as well as corporations like Sony and others in the audio business.
