You can literally point to artifacts in a spectrogram which exist within the range of human hearing with many lossy codecs. It doesn't even have to be subjective.
The question is can you hear those differences, to which the answer is basically no, for a modern codec at high enough bitrate. "enough" is 128kbit or more in blind listening tests.
No one here is arguing that modern, high-bitrate codecs aren't much better at producing imperceptible artifacts. But 128kbps is absolutely not enough in blind listening tests, 128kpbs typically produces a ton of perceptible artifacts. You're just making that up.
To a “trained” ear that is listening out for the differences? Sure, those are perceptible. But those aren’t normal people.
