Yep, so you’ve discovered that the max7219 pcb’s can be wired up differently.
As to the luma.examples, mostly they are targeted to work with marginally bigger screens than 32x8 pixels. The main problem is getting a ttf font that works at such small pixel size: I think that is why the Bitcoin ticker doesn’t quite fit on the 8 pixels of vertical height. There are some examples in the luma.led-matrix repo that are specifically targeted at led matrices and seven segment displays

python3 matrix_demo.py --block-orientation 90 --cascaded 4 --reverse-order -9 - this works, so it appears to be the --reverse-order -9, not figured out how to do the same with these examples

So Demo is working... this now makes me think that not all these examples work on all screens... I thought the code took account for the screen.
