Blind instantaneous comparisons between anything but speakers are meaningless. As many have explained before me, it takes time and experience to hear subtle differences and many people don't hear them at all.
When I started out recording music 50 years ago, it took a few years and countless hours to hear differences between microphones, preamps, equalizers, compressors, etc. And then even more experience to hear differences between otherwise identical microphones and have my favorites.
Long time audiophiles go through a similar process of learning to hear differences that most people don't notice, even with prompting. Whether it's turntables, cartridges, cables, amps, tubes, etc. everything has its distinct sound if you can hear it.
So rather than use your inability to hear as a cudgel against those who can, you might consider learning to listen better. It will be very rewarding if you can accomplish that.
