Listening tests are a mug's game. Once you cross the rubicon you can't listen for enjoyment any more!
Let me comment on that since I am clearly in that position.
To apply my training to hear artifacts requires extra energy and concentration just like any task you focus on. All I have to do is turn that off and all is well. I can enjoy content with fair bit of artifacts and still be OK.
However, there is a threshold above which, I don't need that extra energy and the artifacts do interfere. Last night for example was watching a bootleg version of John Oliver's monolog. Whatever they had done compression wise, was causing the vocals to exhibit distortion that i am quite familiar with (vocals are actually quite difficult to encode with "music" codecs). At first it bothered the heck out of me. I searched for the official/better version but could not find it. So I watched the long episode that way. I must say I would get into the content enough to forget about the artifacts but then it would come to surface from time to time.
US DBS radio such as XM bother the heck out of me because the artifacts are hugely audible to me. It is suffering to listen to it.
Fortunately the general level of artifacts in typical online content is low enough as to this not being a barrier. I can for example listen and enjoy tons of Youtube music videos. In my car I stream Amazon Prime and it too is very satisfying. On the other hand digital FM talk shows do have sufficient artifacts to bother me.
So I say what you say is not the case most of the time given the state of fidelity around us.
