I do use HiFi for music. But programs are not features, they are the means of dealing with the shortcomings of HA technology that can’t make the decision to switch on its own.
Interestingly, when I looked at the amplification diagrams for me HA’s, the higher frequencies were almost identical while the general program actually boosted frequencies somewhere in the 200-300 Hz range (can’t remember the exact frequency range emphasized. Struck me as odd that the flanging general setting was set this way.
