The Galaxy Round, Samsung's first flexible OLED device sports a 5.7" Full-HD (386 PPI) Super AMOLED display is already shipping in Korea and even reviewed and tested by the display experts over at DisplayMate. Engadget now posted a short hands-on review of this device, see link below.
Engadget does not mention anything about the display's quality, only about the curvature ergonomic and mostly talk about other features of this phone. This is a shame as DisplayMate says that the curve display is a major breakthrough - mostly because it reduces ambient light reflections and so improves screen readability, image contrast, color accuracy, and overall picture quality. It'll be interested to hear what more regular consumers say about this display.

It's a flexible display, but it cannot be flexed by the user, is has a fixed cuvature as you say.
Is the display genuinely flexible? It looks to me that it has fixed curvature.
