Answer

As the manufacturer does not differentiate between GTINs, it is not guaranteed according to my research. It is possible that an older firmware is also delivered, as I cannot trace which ones were produced when and which were just delivered by one of the suppliers. Otherwise you would have a 30-day right of return. You can find more information about this [here](https://www.digitec.ch/de/guide/7)
