Storyline 360: Background images more pixelated than images inserted-as-objects

Hello,

I've discovered a disparity between the compression of images inserted as objects (via insert-->picture) and those set as Backgrounds (via design-->background styles-->format background).

As you can see in this preview, the inserted image is of a much higher quality that the same image set as a background.

Closeup - inserted as object

Closeup - Set as background

All output is set at 100% quality like so:

It's quite strange and is now making me second guess all the decisions regarding using backgrounds in templates.
