Here is the response from our department responsible:

We could only find two models in our offer (94i and 94i Plus). The difference between the two is the streaming services that the Plus model has, but the normal model does not.
Deezer, Qobuz, Spotify, Tidal, Amzon Music.

"Connecting to the world - the new edition of the Roberts Stream 94i Plus can certainly be shown off. In addition to all the features of its predecessor, Stream 94i, it now knows the most popular streaming services personally."

Other than that, everything is identical to its predecessor, the 94i model.
Nowhere is there any information about the device's streaming model.
