This is correct more or less. The Ikea hub has had the ability to bridge its zigbee devices to Matter for a while now. So in my case, Apple Home has no idea my lights and switches are not Matter, they just show up there even though they are actually zigbee.
Ikea recently did an update to enable the hub to be a Matter controller itself (over thread or Wifi). This means you can add matter devices to the Ikea hub directly and use the Ikea Home Smart app the control them instead of Apple Home or etc. You can add non-Ikea matter devices as well as Ikea matter devices (when they are released).
