Self-answer here, as I spotted a big clue lurking in the bottom of my FM autogenerated sieve code under section

Code:

  ### 6. Sieve generated for calendar preferences

which led me to Bron's blog article on automatic invitatation processing mentioning the Messaging Engine generated X-ME-Cal-Method header. Now I use the code

Code:

if exists "X-ME-Cal-Method"

and it correctly identifies both Google and Microsoft (and one would hope Apple, etc etc) iMIP messages.
