No, of course it's not even. There are different degrees of gradient on different devices. Some are more even, some less. Going by your photo I'd say mine is a bit more even, but far from uniform; of course it's all very subjective and things don't look exactly the same way in real life as they do on photos. If even the slightest gradient bothers you, then the Oasis 2 is probably not for you.
