    It only seems a nightmare. Look at the lens shapes of the iPhone 6 camera. If you take a non-flat sensor surface into account with this ray pathes, you might be better in shading and CRA. It's a complexe system!

    While there are benefits to having a curved die, the cons are staggering. You have CFA, ulenses, trenches, optical stack processes that need to be modified and they do not work well on non-flat surfaces...
