That's possible I suppose but it's not the system followed by for example video card manufacturers where driver version numbers are the same across the globe. I think it would make things very confusing for a company if they had differing firmware numbers across countries. Having said that they often have different numbers for the TV's themselves in different markets so who knows! I might have to ask LG.
