Configuring the new display modes in Drupal 8 I like very much that in Drupal 8 you can create your own display modes (i.e. not just have "Full" and "Teaser", but create your own) and that you can reference Content via Entity Reference fields within Content. It's really neat and allows me to add arbitrary lists of content on pages and have them render as I like. EXCEPT there seems to be one small issue - the rendered entities always start with the title linking to the Content. There doesn't seem to be any way of getting around it. 

Apart from creating my own templates for my display modes, is there any way I can prevent the Title displaying when I render Content in another piece of Content using an Entity Reference? This seems to be an oversight with a very useful bit of functionality - or am I missing something?
As you've found out through comments, the title is currently hardcoded.

The reason for that is that the title isn't controlled by the view mode in the default behavior. It's whether the node thinks he's on his own page vs. not. A behavior that's not easily configurable.

Would have been nice to fix that but like many other things, we didn't enough time.

Apart from using templates to do, you could also consider to use Display Suite, just like in 7.x, it allows you to control the title, pick from different layouts and so on.
