Digitec did some research for me. It is the 5.0 model from 2021, but it does not come with the thin transparent 2021 cable but with the grey 2021 cable and the Connect Box is from 2020 (it says so on the box). The frames from the 4.0 model also fit the 5.0 model because the frame is the same width.

I think it is the 4.0, as there is no 32" version for 2021.

It is the new, thinner version 5.0... the thickness seems to be the main difference.
