Trying to fix the 'Oops No Help File Found' issue (see also https://github.com/qgis/QGIS/pull/5844) it appears to me that some 'options' which show up in the options DIALOG are actually not stored in the settings.
This makes that this test to find Documentation paths fail:
https://github.com/qgis/QGIS/blob/master/src/gui/qgshelp.cpp#L44

To check:
- make sure you do not have any profiles (so remove .local/share/QGIS)
- start QGIS
- have a look into Options/System/Documentation paths and see that there is an option:
http://docs.qgis.org/$qgis_short_version/$qgis_locale/docs/user_manual/
there
- have a look into the Options/Advanced/Advanced Settings Editor and see that there is NOT a key
"help/helpSearchPath" in the settings.

The options dialog is filled here:
https://github.com/qgis/QGIS/blob/master/src/app/qgsoptions.cpp#L302
so for that reason you see "http://docs.qgis.org/$qgis_short_version/$qgis_locale/docs/user_manual/" in the dialog.

So Question: how do we make sure that these 'default' options show up both in dialogs AND in the settings, ALSO when a new fresh profile is created
See #17598 this issue: https://issues.qgis.org/issues/17598

Another question: WHEN you start with a clean default profile, should a second clean profile not have the same settings then?
In attached image I start a fresh default (left) and a fresh 'secondprofile' right. As you see the settings are very different.
