I wasn't able to find any date offering MH on a KUL-CDG itinerary, but I finally found MH offered as a KL codeshare on KUL-SIN when searching KUL to BER with KLM.



I selected that flight - in "Light" - and even when logged in, the website resolutely tells me I have no baggage allowance whatsoever on KUL-SIN-AMS-BER - while happily showing my 2 checked pieces as Platinum for the return flights which are all on KL metal:


Moreover, it tells me that baggage can only be paid for at the airport!



This would seem to confirm Gajan's report above.
