Audio engineer here, it’s a trainable skill that takes a long time with comparing audio side-by-side
At to some point you can but after CD-quality you cannot. Did you read the article?
As sound engineer you should know that you use high quality to record but it makes no extra sense after CD-quality to listen.
if listening to music from a “good quality phone” is enough for you, good for you. But why would you need to dis people who are craving for a better sound ?
Listen to a standard mp3, then listen to the same song as 32/96k FLAC. I bet most people can hear a difference. But no worries if you can’t, its not a big deal
Mp3 is not CD-quality. As sound engineer you should know the difference. MP3 is old lossy format and you are comparing it to loseless.
There is people that can hear those differences in certain corner cases.
Also you are not defining any specs for mp3 but you are giving specs for FLAC. Why?
Can you hear difference between CD-quality and 32/96k FLAC? If you think you can then you are audiophile and not sound engineer.
