Update: multiple vendors who seem to have contact with the company have used the pronunciation /ˈplætnəm/ or /ˈplæʔn̥əm/, in other words the same as the “other” Platinum and the metal platinum.
One guy, who I believe is Italian, did say the gn like Italian but the rest of the word like English, /ˈplætɲəm/.
So it seems clear it isn’t /pləˈtɪɡnəm/, but the fact that it has a silent g certainly doesn’t help differentiating from the other Platinum.
