For the investment of one image, maybe a second image might have made your point. I don't like curved displays either, but I observe many widescreen photos offer a distorted view of the scene taken on a large flat monitor, since the lens is a compromise as is printing on flat media, and so the image as presented from a wide-angle is NOT accurate, any more than a curved screen of a 55mm lens would be. The problem here is horses-for-courses: if you have a wide curved screen then you should ask your digital devices to render images as if they are being displayed on a curved surface, not as if they are flat.

Anamorphic lenses should be projected/presented on curved surfaces and packages like Hugin will render images which should look pretty good on a curved surface of a known radius, assembled from sets of non-curved flat images put together in a panorama. Or apps like Bimostitch on android, which looks to use the same algorithms.

I don't like curved screens because I haven't learned to rotate my head the way needed to deal with content on the edge. I like dual monitors in a V more than a single wide-screen because they can be independently desktop-panned, only some widescreens do this (by s/w rendering it as two heads)

For some work (Audacity - audio editing, and related video work) a wide screen is fantastic. Horses for courses.
