ATK did mention SV quite a while ago : when the SVSupreme was King and very little else out there :they showed a SVSupreme off but didn't cook anything out of it. did their usual wincing at the price.
Ming Tasi on SimplyMing actually did a 125 salmon w olive oil dill etc using a food-saver system at least.
no studio show however has used a SteamOven to my knowledge. Restaurant based shows of course did.
CK's metrics will be noted by who leaves the Old ATK to join him in his Boston warehouse
remember : these are scripted shows. the scrips are designed to reinforce the audience.
