I work in Film Postproduction and work as a soundesigner or re-recording mixer and also mix music from time to time.
In audio production you can really feel the difference between 16 bit Audio and 24 bit. Just like in photography were RAW only really makes a difference when you start to manipulate the data you really start to hear the difference between 16 and 24 bit once you work with recordings.
24 Bit allows more “shades” of loudness between the loidest signal and absolute silence. This means the above statements depend on the dynamic range of the recording, which is arguably too low in these days.
As an output format 16bit should be enough for most scenarios and except for a few edge cases hearing the difference of a well mastered 16bit recording to the same thing in 24 bit should be nearly impossible.
This however refers all to uncompressed audio. Depending on your audio gear you can definitly can hear a difference between uncompressed/lossless and lossy mp3 compression even at 320kbps. The same is true for 330kbps vs 128kbps mp3.
I must admit that I cannot differenciate between uncompressed and opus 256kbps.
If you do anything that needs audio compression I strongly recommend looking at the Opus Codec
