Denemo is currently outputting \version "2.16" unless you set
Score->Score Properties->Paper->LilyPond Version

(eek!, that is some horrible old built-in thing)

Denemo does have code for detecting the installed LilyPond version, but
it has been disabled for a while now due to some complications (with
windows I would guess). There isn't supposed to be anything in Denemo's
lilypond output that would fail in 2.17, but, of course, that is a
moving target. When the next stable release is made (2.18) we would
upgrade Denemo if needed.

The LilyPond installer creates an uninstall script in your ~/bin
directory which you should use to remove it. AFAIK it is the same as
removing the scripts in ~/bin and removing ~/lilypond (although there
are font caches somewhere once you have run LilyPond, but they may be
ok).

yes - see above, that is hardwired until you change Score->Score
Properties->Paper->LilyPond Version
