I am now going to answer my own question:
According to Apple Developer Support, IODisplayConnect is no longer supported on Apple M1 systems.
In order for me to get to the display information I had to look for IODPDevice to iterate on. Then get properties from the child service of the IODPDevice.
Be aware that the IODPDevice service does not contain the same data that IODisplayConnect did.

So it turns out that IODisplayConnect is not supported on Apple's M1 systems.
Look for IODPDevice then iterate as needed.
