Thank you Andy for the detailed info. I will look into the Python’s trace functionality.

By the fact that you're using the built-in server (i.e. the ParaView GUI and pvserver run in the same process space) you have access to client-side information like representation type but that stuff is only available after you've fully executed the programmable source script.

I found out that after I press The Apply button I can modify the script to set the representation type to ‘Points’ but if I place a GetDisplayProperties statement at the end of the script initially to gain access to these properties, I will get:
