Kind of funny that we trust Google's index of the whole www to take us to manufacturer's legitimate website, but don't trust Apple's own search of their curated store.
They link directly to the app. They almost certainly have relevant QR codes in the manuals to go directly to the app downloads. You can find the official app listed by "Samsung Electronics", where the "scam" app is by a third party.
There are a lot of problems and egregious abuses in the app store (made much worse once recurring subscriptions appeared), however this particular thread is not convincing. Some third party made a control app for Samsung TVs. There is nothing wrong with that (and it does not, contrary to claims, misrepresent itself or even clone the official app, beyond the most superficial of mainstream design choices). There is no reasonable reason to think that the app is by Samsung. I don't see how it's a scam in any way.
For someone to miss the Samsung app and download this, then agree to a subscription and pay, is something that I don't think many people would do. And it certainly isn't a fault of the store.
