Is there any chance that the color for those elements is coming from a Style rather than background? Your software engineers can probably identify if the color is coming from a style.
With WPF there are so many levels in the hierarchy I sometimes have trouble finding the right one. If Background shows "(Null Object)" the two most likely reasons in my opinion are either the background color is coming from something else (e.g. a Style) or you need to select something at a higher or lower level. I hate WPF...
Sorry I don't have a more definitive answer. This is a tough one.

Most likely, they are using Custom Styling in their application. Hence the Background is appearing as Null Object in Object Spy.
