It’s different from person to person!, whether the curve is good or not.
I have a ruler flat 55” OLED TV as main monitor. It’s perfect for me. I’m like… 1-1.5 meters from it where I’m closest to it, haha. The edges are further away. It’s fine! – imo / ime.
(The need for the curve is also subtly different depending on how the panel was made. I tried a flat 43” IPS 4K monitor, expecting IPS to be good. And it wasn’t very good. The IPS features in that panel were large enough to affect viewing angle.)

The amount of curve also varies a lot between models so there's some nuance even within that. The curve might be as strong as 800R or as weak as 2300R depending on the monitor, where the number corresponds to the radius of the circle the panel follows in millimeters.
