Question about Samsung The Frame QE65LS03D (EU)

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 :)

(No guarantee for correctness of the information)

Hello,
I was also able to see from the description that there is a difference in the sound of the TV (Dobly, etc.).
Thank you

I would also be interested... According to Samsung, the last 2 letters AU stand for
- A = First version / Serif only: Colour White
- U = function or design

... but what does that mean?
