Richer information in the microdata than in the visible content in the HTML page: what is the good practice ?

Hello,

I have the following question :

Working in a media with a video database, we have a lot of fine
informations about the video : video properties,  user interactions,
comments...
In the HTML page, only a small subset of those informations will be visible
to the reader.
Should we publish all video information we have as microdata/schema.org in
the HTML page, even if they will be invisible for the reader ?
What would be the impact on a SEO point of view : negative, neutral, still
positive, when the microdata/schema.org description of an object is richer
than the visible information.

This question is about video, but also applies to persons, events...

Regards
Jean
