You have it right , though mura is generally used for localized cloudiness in a panel , rather than synonymous with moire . I find it intriguing that most people describe the visible pixels as oily . I guess because of the coloration . I liken it to a freezeframe of old TV static , but very dark and colorful . If I was or end up producing a PSVR title , I ' d always keep something onscreen rather than letting it go to standbygrey . Almost anything is enough to prevent the eyes from becoming ultra lightsensitive to the barelylit OLEDs . The horrible thing is that this pattern is something screenbased to focus on , creating a jarring mental transition out of VR . I really dislike it when a game does this while loading .
