Simple answer is NO even as a WP1 couldn't get in one has to be flying F to get in.
Are you sure about this ? I know Y pax can access the F lounge at DXB. There were a few people standing behind me and my wife as we boarded EK in F and when asked if they were flying F they said no they were flying Y but they boarded from the F lounge. Perhaps they had EK status ?
Never had an issue with F lounge access just no access to Free Spa Treatments as offered in MEL or SYD F lounges so in the context of the OP the answer is no
Well, you learn something every day... passed through the FLounge in DXB last Nov/Dec - WP and flying F both times and never even knew there was a spa there!
