So I'm up in the air between buying a white one or a black one. I want the white one, but I realized when I did some comparison side by side and I noticed the black version has a brighter display than the white version. I made sure that the brightness and any other settings were the same. I've compared it with a few different units at the store. My question is does anyone else notice this could maybe a flaw or hiccup with the ones I saw?
