I ordered the same Osram dimmable bulb directly from bulbamerica.com, who listed this bulb as having a color temperature of 2700K like Amazon. Once I received the bulb and tried it out, I also noticed that it had a much whiter light than I expected for 2700K. Well, I looked at the label on the packaging and the label on the bulb itself and guess what? They sent me a 3000K bulb, which explains the whiter light. I bet they sent you the same 3000K bulb. The color temperature is listed right on the base of the bulb if you want to check. I've sent an e-mail to firstname.lastname@example.org telling them that they either sent me the wrong bulb, or the specs on their website are wrong.
Just thought you might want to know the possible reason behind your "whiter" light.
