Technically, wayland does not have a display server. It has a compositor, which could be considered more equivalent to X11 window manager than to X11 server. The compositor handles display and input by itself (using KMS, DRI, libinput, etc.). Examples are Gnomes Mutter, KDEs KWin and Sway. Among other things it means less context switches and synchronization when trying to display something, smoothly.
