I’m not even sure what you mean here? Our eyes can see about an octave of visible light (400–790 terahertz), we can hear around 10 Octaves, so I’m not sure what ‘fidelity’ means in this case.Our ears do not have the same fidelity as our eyes.

You are very lucky then that you can be satisfied that your £100 Dac and £200 amp playing Spotify can ably compete with a £10000+ system playing HI Def, certainly should save you some money.
And even that 20bits is a stretch. It assumes your ears can withstand 120dB without damage. For sustainable dynamic range, we're probably maxing out at around the 16bits of CD. Perhaps with peaks to 18 bits if not continuous.That several hundred THz more frequencies than the audio band
As for dynamic range, that’s pretty comparable to audio: about 20 bits of sound or light

Got a link /source for that mp3 to mqa conversion.bit please?He is right about streaming companies trying to save space and upsampling lossy/compressed music. Not sure about all of them, but Tidal did get caught doing so, including mp3 to FLAC MQA automatic conversion... That's one service I wouldn't trust anymore...
I've seen at least 3 threads about this issue, which I cannot find right now, but there is also the Goldensound (ex-ASR member) video where he claimed that he posted his low-res music on Tidal as an artist and they've upgraded it into master quality/MQA... Another guy downloaded some FLAC files from TIdal servers using 3rd party app and tested their spectrum using a tool called Faking the funk or something like that. They all failed the lossless property tests... I'll try to find those posts..Got a link /source for that mp3 to mqa conversion.bit please?
It's the same for ears, there are muscles that tighten at high sound levels and reduce the movement of the bones coupling sound from eardrum to inner ear. They protect you from deafening yourself when you shout.... And the eye has a helper, the iris: it actively limits light entering the inner eye, helping increase dynamic range.

I may be mistaken but I don't think any of Goldensound's investigations involved tidal serving up a file provided to them as mp3 as mqa. His investigations showed mqa was not lossless (yup) and that if the file provided is mqa, their middle tier hifi would serve you a 16/44 undecoded mqa file.

That's the thing,
the difference between a movie on Blu-ray vs DVD viewed on a good 4K television set is immediately evident, with music, High-Res vs CD vs Mp3 (320) not so much or not at all in many cases, at least not to me.
