No, it's equivalent to having a bright image for a short period. So for the cathode, it's no worse than having a bright scene for a fraction of a second. For the phosphors, it's not enough to produce visible darkening even after many cycles. The only time visible darkening happens is in studio monitors that run 24/7 with a test pattern on, or a message display that has text 24/7, or a video game in constant used with permanently stationary image elements / menus, etc.
