Guacamole leverages libvncclient for VNC support, so it supports anything that libvnc supports. libvnc, in turn, supports things documented in the standards plus the more commonly-used features, but definitely lacks support for some of the non-standard things that various servers have chosen to implement. Pretty much any of the above can be configured with more compatible, standard options, but several of them support customizations and additional features.
RealVNC is probably the least compatible of those ones - they have done quite a bit of customization to their server and client and support many things on top of the VNC standard. This is fine - I'm not saying anything bad about - one of the strengths of VNC is that it is extensible, but it introduces interoperability challenges. -Nick
