I am listening to a 96/24 track on Qobuz at 2766 kbps (kilo bits per second). Compare that to Apple Music at 256 kbps AAC or MP3 typically at 320 kbps.
Another variable is the quality of your network accessing the online content. Noise can be added along the way if not carefully chosen.

44,000 samples per second times 24 bits per sample = 1,061,760 bits per second = 1062 kilobits. By the Nyquist Theorem that should be enough. If that's right, only the Qobuz is sufficient but I may be overlooking a lot of stuff. Maybe 20 bit samples are sufficient. I'm not an engineer.
It's never too late to turn back the clock.

There is far more to what's involved with audio quality than merely meeting the Nyquist requirement. 44.1 requires brickwall anti-aliasing filters that cause time base distortions and pre or post-ringing into the pass band. Higher sample rates afford more gradual filter slopes and avoid such.
From what I've read from some experts, 20 bits is indeed enough. There's one inmate engineer who states that in his tag line. 24 is merely the next standard value for commercially available digital components today.
Any time marketing is involved you will have people touting features that are neutral or negative.
