I can give some results from non-NixOS: 

1. Debian Jessie + Okular:
   -> worked

   $ okular --version
   Qt: 4.8.6
   KDE Development Platform: 4.14.2
   Okular: 0.20.2

   libpoppler46:amd64  0.26.5-2+deb8u1

2. Debian Jessie + Nix + okular-4.14.3 from nixpkgs.kde4.okular,
   Debian Jessie + Nix + okular-16.04.03 from nixpkgs.kde5.okular

   Did not work at all: (a) okular cannot open any file and
   (b) okular turns the audio-mixer to 100% (wtf?) and plays an error-sound

   So, Nix okular-packages seem to be completely broken when used on
   non-NixOS.

   Error-message of okular when trying to open some PDF:

okular(32461)/kdecore (trader): KMimeTypeTrader: couldn't find service type 
"okular/Generator" 
Please ensure that the .desktop file for it is installed; then run 
kbuildsycoca4. 
okular(32461)/okular (app) Okular::Document::openDocument: No plugin for 
mimetype '"text/plain"'.
