Well, we'll only be able to see it if we either compare it side to side or just get the other and compare photos. That would be hard to do for photos, becuase depending on the lighting the cream or whitecould show up differently than it is in real life.
When I think of white I think of blaring white, so it's like a more "cold" color. Not the warm creamy color. One way to think about this is christmas lights.
When I walk Max during christmas, many of the neighbors have lights. Most have the common "cream" colored ones, which look very cozy yet bright. Other have white lights, which tend to look "cold" and bright.
I'd say the difference could be like parchment or old paper vs. new printer paper
