So, I got in touch with the Samsung chat (or chatbot).
Here is the explanation for the 2 different product names:
Q65LS03DAU 2024 labelled in the product description as GQ65LS03DAUXZG =
German model
QE65LS03D 2024 labelled in the product description as QE65LS03DAUXXN = Austria/Switzerland model
Austria/Switzerland model
Different country designations for the same model, no qualitative differences. There may be an adapter for the German (cheaper) model for the CH power grid.
I have ordered the cheaper offer incl. 5-year warranty.
Hope I was able to help :)

A wall bracket is not included as standard with the Samsung TV "The Frame QE65LS03D (EU)". however, there are special wall brackets that are compatible with this model.
The wall mounts offered by Samsung, such as the "No-Gap Wall Mount" or the "Slim Fit Wall Mount", are compatible with the model "The Frame QE65LS03D (EU)". These mounts are specially designed to integrate the TV into the wall and ensure that the TV can be mounted flat on the wall, which corresponds to the design of "The Frame".
