I don't know if you are testing for the same thing. Your test consist of highlighting the losses with some audio processing. But could you do the difference in a blind test? Take your lossless files, convert them to lossy audio, and back to lossless. Mix the new files and the original files randomly with a script or by asking someone else, don't look at the sizes or spectrograms, play the couples and see if you are significantly better than guessing correctly which one has been loosely compressed 50% of the time.

It does not really matter to me, I enjoyed the songs either way. I even have a few 128kbps mp3 albums. Storage is cheap and my collection is only around 500gb. I still keep lossless just I have perfect rips of my favorite movies. Because lossy is lossy and I prefer to have something as close as possible of the original release. I still remember being happy about radio quality song and vhs, now not so much. Maybe they’ll discover a way to repair and enhance hearing, and we’ll look at lossy codec the same way we now look at 360p videos.
