Labels in Custom Layout Report Quick View + Report bg colour

Hello,
Actually two questions, slightly related.
1. I make pleasantly use of the custom layout feature for Report Quick Views. It's easy to add fields, however can't find a way to add labels to the field. Either the form field label or a custom label. I would be happy even with a custom text element, but even that does not seem to be there.
See screenshot attached. Eg field Date of Birth has no label option.

2. And can we give a custom colour background to reports? I tried this in a page, you can give background colours or images to panels, but not if you embed the report. So next I looked at the report config options, but can't find such an option. It's always a light grey background. Screenshot 2 showing an embedded report in a page
