Curved screens are only good when you get really large and that is to actually account for the distance the light has to travel from the projector before it hits that part of the screen.... So yeah, once you get large enough that you have to worry about the speed of light and how much it expands due to screen size, THEN you can worry about curved screens.
TVs with curved screens is 100% snake oil marketing crap.
At least with Atmos, SOMEONE will get a benefit from it. That group will be very small, but compared to the curved TVs at least there is some level of merit (not much).
