Theoretically lets say that 150 fov is the best compromise to reduce Fresnel artifacts, god rays etc. If that was true and at 150 fov it looks incredible but at 200 fov it is 30% a light show inducing headache mess and 70% incredible. You would still prefer 200 fov? I think that would equally annoy all those that would take a compromise.
Of course this could be worked around by designing games so they do not have extremely high contrast scenes. Although the movies would still be an issue.
It is just a theoretical showstopper so don’t stress too much
