the outers will tend to be less bright than the inners, but both of those look less pure white than mine (also 8500k) while in DRL mode like you have it - but I got the 1st generations.
I don't think you got faulty ones... if you're not satisfied, I'd ask for a refund. I actually like my inners being brighter - it's looks pretty unique. But mine are slightly whiter than those in daylight.
