The Nyquist-Shannon sampling theorem isn’t subjective, it’s physics.
Your example isn’t great because it’s about misconceptions about the eye, not about physical limits. The physical limits for transparency are real and absolute, not subjective. The eye can perceive quick flashes of objects that takes less than a thousandth of a second. The reason we rarely go above 120 Hz for monitors (other than cost) is because differences in continous movement barely can be perceived so it’s rarely worth it.
We know where the upper limits for perception are. The difference typically lies in the encoder / decoder or physical setup, not the information a good codec is able to embedd with that bitrate.
Newer fractional arithmetic encoding can get crazy
Why use lossless for that when transparent lossy compression already does that with so much less bandwidth?
Opus is indistinguishable from lossless at 192 Kbps. Lossless needs roughly 800 - 1400 Kbps. That’s a savings of between 4x - 7x with the exact same quality.
Your wireless antenna often draws more energy in proportion to bandwidth use than the decoder chip does, so using high quality lossy even gives you better battery life, on top of also being more tolerant to radio noise (easier to add error correction) and having better latency (less time needed to send each audio packet). And you can even get better range with equivalent radio chips due to needing less bandwidth!
You only need lossless for editing or as a source for transcoding, there’s no need for it when just listening to media
Except Opus. Beats it at most bitrates
You literally can not distinguish 192 Kbps Opus from true lossless. Not even with movie theater grade speakers. You only benefit from lossless if you’re editing / applying multiple effects, etc, which you will not do at the receiving end of a Bluetooth connection.
That’s more than a codec question, that’s a Bluetooth audio profile question. Bluetooth LE Audio should support higher quality (including with Opus)
