No. The closer Proximity of the ends to the projector would always result in a "flaring" of the sides. Even Anamorphic lenses are not immune to that effect.
A curved screen was/is primarily intended to help reduce the effect of ambient light coming in from each side, and/or to focus projected light back to within a specific viewing area. Some High Gain screens utilized curved design so as to equalize the brightness difference between the center of the Screen and the edges.
The amount of "flaring" is of course dependent upon the degree of radius of the screen, and many times the overspill at each corner is slight enough that effective Trim masking rakes care of such.
Why do you need a curved screen?
