AFAIK if there's a name stored in the SIM card it will have precedence
over the ones stored inside the modem. And the ones that network sends
are probably most reliable. I have to look though the specs if there's
any information on this.

Anyway the point is that in most situations we should have a correct
alphabetical name for the provider, right?

In this situation we simply have a miss in database search and user is
presented with all the available configuration choices. Can you provide
some real life example where the long alphabetical form is misleading
and would cause selecting wrong operator?  At least the devices I've
tested return reliable results, but they are so few that I can't claim
anything based on those.
