Why we won't know how visible the iPhone Duo's crease is for a long time

Apple’s upcoming iPhone Duo features a nano-textured matte display that reduces light reflection, making the fold crease barely noticeable in early hands-on tests. However, the crease becomes more pronounced with repeated folding, as seen in other foldables, and cumulative damage over months may increase visibility. The device’s long-term durability and crease performance will only become clear after widespread consumer use.
