I'm looking at doing a day trip BKK-HKG-BKK in April. The online menu, if it is to be believed, specifically shows caviar in both directions on these two short segments.

I haven't flown EK F since just before the lockdowns started, and it's been about ten years since I did this specific route when my then partner did indulge in a shower, with my encouragement of course. On that occasion they had Y d'Yquem, the dry Yquem, one of my favourite wines.

IME the shower comes into its own is during irrops, such as when you find yourself with a much shorter connection time than expected. Otherwise it's a bit of a gimmick: that doesn't exclude me from indulging though!
