I have one good bulb and was thinking of getting another matching bulb to put into my newer car but I know there is always something better.
The Osram CBIs are much better than the Ultinons. The only Philips bulb which might be close is the 85122XV.

Even if the bulb doesn't color shift, they do get dimmer with time. I would only replace in pairs
