If you look at all of the high end cars, their headlights are never above 5k and since they have higher quality bulbs, they have a broader temperature output. I would say most high end cars range from 4500-5000k temperature range. I run 5ks in my car, and whenever I go alongside a premium car mine are more blue still then theirs.
Most Osram/Sylvania OEM bulbs are 4700k temperature. The color you see is from the cut-off shield.
