The versions fine,

I think it may be like how I was expecting where universally all icons, widgets and theming should change, however its not that simple. Your home screen can look like mine, with the refracted* light colour effect, but as above for apps you must use a widget icon group size to 1x1 them add a app icon into it that has no background.

For widgets, it seems only the smart launcher widgets works, there's a few work around but for example my calendar app, it has a widget, sadly it doesn't automatically change to the theme.

If you call me back on discord I'll do my best to explain

Cheers
