Of course CX wouldn't know since you are issuing this from a travel agency and the TA might use public fare, private fare, net fare, etc. Who knows what Q fare the TA will use?
Some Q class tickets can be upgraded to I class, some can't. Without knowing the fare basis, no one can give you the answer.
