The supplier has responded but unfortunately does not have the information requested.

I checked the specifications but could not find the compatible models. I found this info in the description of this cable on a website: A Samsung One Connect box is included with all Samsung TV models 7000-9000 that are from the year 2016 onwards.

So the cable should be compatible if you already have the Samsung One Connect box with your TV, TVs from 2016 onwards if the model was Samsung TV model 7000-9000 (I checked the manual of this TV and it says it comes with One Connect).

In summary, we can't guarantee that it is compatible (no official confirmation) but according to the specifications it should be compatible.
