Fortunately I managed to solve the problem. Seems that it's a gamma correction problem. The PNG file allows you to set gamma correction information and Silverlight and IE seems to handle it differently.

This page explains the problem and saved the day. This tool as also necessary to remove the gamma information from the PNG.

Hopefully this information will be useful for someone.
