Is Kitware VolView support Grayscale Softcopy Presentation State?

Hello,
I have ORTHANC server where I want to render DICOM documents that contains Grayscale Softcopy Presentation State text and graphical annotations. One of the possibilities is to use a ORTHANC VolView plugin. However, I was unable to display the GSPS data.

Is Kitware VolView support Grayscale Softcopy Presentation State?

Thanks!
