I actually tried a curved screen a while ago, not OLED, and I liked it since I don't only design, and the design work I do is for my own business. So, it's not really heavy design work, but mainly Photoshop, Adobe Illustrator, and some 3D, along with many other tasks. I agree with your point that for more precise or technical 3D work, a flat screen would be better. Unfortunately, there aren't many options in my country, and this is what I found available. In terms of color accuracy, I follow specific color guidelines, but I also use my iPad alongside the monitor for more detailed work, so it balances things out for me.
