OTC Hearing devices sound quality for acoustic grand piano performance?

Has anyone tried an OTC hearing device and found it sounds realistic while playing acoustic ground piano? I searched for over two years and settled on white X moment 440 which is the” Sort of best” Sound quality of playing acoustic grand piano. Be aware on this topic I’m specific about how Hearing devices represent live playing of acoustic grand piano…. Setting aside listening to recordings or playing digital piano.
Does anyone have hopefully good reports wearing an OTC device and sitting down at an acoustic grand piano?

Slightly off topic: I would say an acoustic grand piano would be the ultimate test for the ability of hearing aids to amplify music faithfully.
