Yes that is much better than most thought it'd be given the performance of other JP developed games on the platform not the least of which was FF Type 0.
I hate to break it you but the UK is the only country in Europe where the Xbox One has anything resembling an equal retail presence with PS4. 8:2 is horrible. In other European countries the gap was even bigger. It's impossible to argue that FFXV on Xbox One was anything other than a massive flop.
