I don't think it ships with a desktop environment by default; I think they're just referring to the Qt framework. If it is mentioning a desktop environment - it's probably LXQt.
I know Microsoft gave Gnome a donation of 10.000$ because they use Ubuntu (which use Gnome) and inside the repo (inside SPECS folder) I've seen gnome-commons to build gnoem stuff.
But yes, this is probably a server distro without a DE.
