Just for the record, I am an embedded software developer and do firmware updates on custom-designed hardware almost daily. So I would say I'm pretty familiar with the processes involved both at a software and a hardware level.
When you refer to "the real technical process" what exactly do you mean? If you're talking about what happens during a firmware update then that's something I could talk about in more detail about (if it's helpful). But I suspect you're asking about what's the process by which the firmware update could influence sound quality. Since that's something you've just postulated I think the onus is on you to explain it to the rest of us...no?
ETA: I don't think of it as "psycho-acoustic doubt", by the way. On the contrary, it validates what you hear independently of any objective cause -- more a case of "psycho-acoustic freedom from worry".
