Hi, welcome.
I tried sudo dolphin & agree that the result is missing icons. May i pls suggest an alternative way of looking at your requirement?
Rather than seeking to launch Dolphin as root, which i presume you wish to do so as to perform root actions on files & directories owned by root not you, why not actually use Dolphin's native Root Actions capability? Mint 17.x KDE has this, & i loved it, but stupidly they omitted it from Mint 18 KDE [as did also Kubuntu 16.04, KFedora 24, & even KDE Neon itself, but it's present by default & working beautifully in Maui]. This is one of the major reasons [though there's many others too] that last year i abandoned Mint KDE & came over to Maui.
You can configure Root Actions via Dolphin's Configure Dolphin menu selection:
Thereafter, if you wish to be able to edit / copy / move / delete any root-owned file or directory, you do it via the right-click context menu in Dolphin:
If this does not meet your needs, & you really really do want to launch Dolphin as root, then i'm sorry i can't help [but i imagine it might be some library file/s missing?].
