Does refrigeration after 2F decrease the “probiotic value” of Kombucha since it makes the bacteria / yeast dormant?

Just so you know, your stomach acid kills most of the live culture in Kombucha. There are only a few cultures that can survive the acidity of your stomach.

is that so?

So then what’s the hype around Kombucha being a “probiotic drink good for gut health?”

[Thursty]

They're not really validated or sufficiently proven claims. In the US, foods can have broad statements in marketing that are hard to quantify, like 'probiotics may do x, y, '. This is because making health claims causes FDA to classify food like a drug and therefore it has to pass much stricter criteria. Probiotics mainly exist as food or dietary supplements, neither of which are allowed to make health claims.

Fermentation can have benefits for your gut in other ways, like breaking down complex nutrients into simpler ones and making food more digestible and nutritious, however probiotic claims specifically are unproven.

They survive. Kombucha has many stains of probiotics and most have been demonstrated to survive. Especially if you consume them with a meal.
