Nah, our displays aren't
that old.
Many models now include "smart" features that do things like motion blur, contrast adjustment, etc that probably do make the picture look better (i.e., "more cinematic") when used normally. These features just clash with niche uses, like vision research and competitive gaming, that would prefer pixel-accurate, predictable updates.
It's surprisingly hard to figure which consumer monitors have what features. There are "research" displays that don't have these features, are calibrated, update in a predictable way, etc, but they're eye-wateringly expensive.
In some sense, we were spoiled with CRTs, which were too dumb to do anything but sweep from top to bottom, left to right, over and over. Of course, it was much harder to generate dynamic stimuli back then too, so it's a mixed bag.
