Thanks, unfortunately u are right.
The odds that this feature will be implemented any time soon in any game are pretty low but thats a thing that is REALLY bothering me.
I spent almost 6K on an entire new setup with the best and newest Hardware to figure out that game Devs are kinda stuck in the last century. Actually none of the triple A titles I tried so far does support such features only a few Indie games.
And of course I do have the most curved, biggest and widest gaming monitor you can have with 49" of 1000R curvature and a 32:9 ratio which makes it even worse. 
Below I’ve attached a screenshot of the view I actually see and than a version which i manually converted to the panini projection.
Obviously it loses quality if its being converted afterwards. Which is the reason that this feature has to be directly implemented into the game but at least you can get an understanding of how much this would improve the overall look and feel.
Note:
If you look at these images on a non curved monitor don’t forget that these effects would be amplified quite a lot on curved ones.
Additional Fun Fact. Many common Game Engines already do provide the tools to use the Panini Projection. like Unity or Unreal Engine.
I don’t know which Engine the FS is based on but it’s likely that it has them too.
