Anything you can introduce into the scene (additional lights, objects) could help to make it more realistic to some extent, but if the environment needs to be totally white, than that's all that the chrome will reflect. Try to use some dirt maps (leakings or dust like) on the specular channel of the material - that will alleviate the problem a little, but still - chrome is 95% reflections, so...
Sorry I couldn't be more of help.
