When flying in QR F, is the service standard the same across all aircraft / destination in terms of pyjamas, amenity kits, champagnes and caviar? Or does it vary by aircraft and route?

I am flying on the 21:05/00:05 flight from BKK on QR829 and wondered if this had a different offering to say the LHR sectors? I am flying on the old Cathay 777 aircraft that QR are using on certain routes.

Thanks!
