This has been true for long haul carriers like Etihad/Emirates for over a decade. I very occasionally have to grow a lanyard and fly business class, and the food is generally equivalent to a reasonably good restaurant, and a very good restaurant in first class (I've heard, I don't rate that.)

Of course if you need to do a 30 hour flight and then get straight to work with no downtime you want it to be. But flying non-economy is really a different world if it's the Aus-Europe/Aus-NA routes.
