For everyone complaining that the high definition graphics aren’t the same in the English or global versions when comparing them to the Japanese one, it’s most likely due to limitations on the graphics rendering from your device. High setting on an iPad mini 2 is identical between both versions and look pretty damn good.
I’m unsure what people define as “blurry graphics” though because what I see is sharp and beautiful. I suppose some things like the shadows could be “sharper”?????
