Does it really matter what the brand is? Really? To most people? There could be just about anything inside that container and 99.99% of people wouldn't know the difference. Do people really buy premium plane tickets based on what brand of soap is in the lavatory? Ohh... this feels soooo luxurious after passing my mushroom risotto into a chemical toilet. A premium toilet perhaps? Better really scrub around the nails after using that thin Surpass toilet paper.
I once posted on FlyerTalk in a trip report a photo of some foamed fish dish where all I did was take some store brand foaming handsoap and give it a good pump out onto a coaster and photograph it. Was a pretty good troll until I admitted it and it got deleted. Apparently it looked really really appetizing to those used to Michelin starred restaurants.
