When you switch channels does the dynamic artwork option need to be enabled to get the poster and logo to show up for local movie files?

Dynamic artwork means that while you scroll through the EPG the infocus (highlighted) media's artwork is displayed and changes. Instead of just displaying the artwork for what is playing.

So Yes it needs to be enabled to work, but if you don't have the artwork stored locally it won't display, you need to run artwork downloader script.

for LiveTV you don't need the artwork stored locally, but you need to enable api's inorder to parse and store show data.
