Yes in the US I used the original 32:9 49" in the store for quite a while and wasn't impressed. Human vision is approximately 200 deg wide by 120 deg tall. Or about 1.6:1. To me 32:1 looked extremely un-immersive, having such a tiny vertical viewing area hardly taking up ant of your vertical view. Like looking through a window blind out into the world.
A lot of people don't realize with a crazy wide aspect ratio like 32:9 and limited vertical, characters, anything with detail will look smaller in the center of the screen since it's essentially just a 27" 1440p monitor with 50% wings tacked on either side. 27" 1440p is anything but immersive.
What do you mean by saying 'un-immersive'?
32:9 48.8" panel will give you about the same height and the same vertical FoV as 43:18 34" panel, but bigger horizontal FoV.
