Does display hat mini support picamera for preview, stream, etc...

picamera has a renderer api and I wonder if I can hook displayhatmini for that : https://picamera.readthedocs.io/en/release-1.13/api_renderers.html

We managed to get PiCamera working on an LED matrix display before, see: https://github.com/pimoroni/unicorn-hat-hd/blob/master/examples/camera.py

The process should be roughly the same, though you'd be pushing quite a few more pixels.
