public string GetPresentationLutInstanceUid()
The SOP Instance UID of the Presentation LUT that was last created successfully using the method CreatePresentationLut.
Once a Presentation LUT is created, a call to this method will return the SOP Instance UID of the newly created Presentation LUT. Therefore, if the SOP Instance UID of a Presentation LUT is needed, it should be stored before creating the next Presentation LUT.
