I looked at the picture again yesterday. I cannot detect any blurring at the edge of the image with my projector.

This means the following: Netflix is preinstalled. However, I have not tried out whether it can be operated with a Swiss account. The app Zattoo cannot be installed. The selection is indeed meagre and intended for the region 'Germany'. This region is fixed and cannot be changed. LG Support Switzerland is 'stupid' or not competent enough to answer this question. I then got myself the Chromecast Stick for Zattoo and Hollystar, etc. Since the Chromecast Stick can be powered via one of the 2 USB ports, it doesn't need an additional power supply. I also installed a wireless HDMI connection. I packed everything into a box and mounted it on the ceiling next to the beamer. The box is then as big as the small beamer :-). All it needs is a 230V socket on the ceiling and the beamer can be quickly removed (magnetic mount) when it goes 'out'.

The filter was not included. Digitec will send it on request. The Smart app region is set to 'Germany'. Cannot be changed to CH. I will get myself a Chromecast stick for Zattoo, Hollystar SRF etc.
