VTK format is not storing rendering information, but only data. In VRML it is different. I believe it's a bug of the VRML exporter of VTK (or it was not a feature of that exporter).
Therefore, the only solution that I see is to either fix the bug or change the opacity attribute in the VRML file manually.
