Correcting MIB2 High Version ST to SC

[paradise17]

Hello friends
I recently updated my MIB1 to a Harman MIB2High
My car is a 2014 5F FR SC equipped with Seat Sound, not the Beats version
Now with the MIB2 High I have the ST image in the car menu and when the parking sensors are active
My question is this: I have the impression that with my old MIB1 unit I was getting better sound quality, in this MIB2 the Subwoofer menu is active and functional, but I read several posts that indicate that the sound file in the MIB has to correspond to the car model because the DSP has several files for each ST SC version etc....
I would like to know if this really makes a difference or if it's just my impression.

Unit requires correct parameterisation & coding. Configuration is vehicle specific dependent on specification

Everything is working, including the subwoofer option, but I have the impression that the sound is different.
I think it must be because it's configured as if it were a ST and in reality it's a SC.
How could I make this change? Is it possible to do it through the green M.I.B. menu?
