Keep an eye on two things; type (LR or ER) and temps. This time of year it's not too hot at 10pm there (departure time) as long as it's an LR you should be fine if you can find a seat, but in summer months it can be over 100F at 10pm....and that can be a problem even with the LR.

I flew 3 DXB trips last mo. and we were not payload optimized on any of them, but we were completely full on all of them out of DXB (not into) and left some non-revs behind. Some did get on however, but there were about 25 on the list.

One backup plan is to buy a Zed fare on Air France to Paris, then get on DL there.

If for some reason (MX usually) they put an ER on it, could be very tight getting out and they might payload optimize it. ER's are ships #7001-7008.

Check the ship numbers in iCrew, flight status the day prior. The 10 LR's are 7101-7110.
