AFAICT it does not only "default" to the DE contained within the live system but rather does not even show the choice screen because it installs by copying/extracting the live system's data and hence, the DE (and other software choices) are already set. See below.

TL;DR: Live Installers do not present the DE selection screen hence it should not relate to the OP.

Is that is what is meant when it is claimed by Greg Wooledg: With the "Live" installers, the default is different"? Calamares introduces a new ball game?
[...]Let me try to clarify this a little bit from my experience as an "advanced" user :)
Calamares is an entirely separate installer that can be invoked from within a running (live) system. It is _one_ way to install Debian from a live system but it is not the only one. It is worth stressing that there is _no_ interaction between Calamares and d-i and that they prsent different screens. Behind the scenes, Calamares invokes an `rsync` to copy the data from within the live system to the target.
For a typical session in Calamares, see [1] for an example from Debian Buster.Now d-i is separate in that it does not run from within the live system but has to be invoked _instead_ of the respective live system from the boot menu. It is, however, contained on the same ISO image/DVD together with the live system's data. The d-i variant used on live systems does not ask for the choice of DE because its software selection cannot be customized like in the regular d-i. Instead, it simply copies the data from the live file system to the targed drive (? I am not exactly sure on this one ?). See [2] for an example from Debian Buster and note the absence of the tasksel screen.
Now the regular d-i shows the tasksel screen and asks for which DE to install. See [3] for an example from the Debian Bullseye Alpha 3 installer.
