Apple HomeKit Wallpaper Sync

Hi,

I have Apple Home/HomeKit configured. I use multiple devices to control the space (Mac, iPad & iPhone. I'm logged in with my AppleID on all 3 devices. I have changed to a custom wallpaper on my Mac for each room in my home. None of these custom wallpapers will replicate over to my iPhone or iPad. All other changes (room names, switch labels, etc) seem to replicate across my devices almost instantly.

Did a search on this issue, the thread I found was from 2017! Apple suggested I create a new thread instead of ask on the old one so here I am.

Is this expected behavior? If so, pretty lame for Apple.
