Don’t forget: if you have Better Blur DX installed, you’ll need to rebuild it for it to work again.
yay -S kwin-effects-better-blur-dx --rebuild
I had to install
sudo pacman -S gtk4-demos
later. I noticed that in the video linked above.
Is this needed? I installed it, to e safe.
Yeah, don’t forget. Klassy, Panel Colorizer and KDE Material You runs as expected. Didn’t noticed any issue so far
Hmmmm 
, i am sorry i don’t use blur effect
Builds and show up here. Did you restart System Settings?
All updated here too 
but apparently two packages to remove colord-kdeand kgammaas neither appears in the Arch repos any longer
Edit: anyone know if any replacement packages are recommended?
That’s the default Breeze wallpaper
Good to know. That’s the only wallpaper in their Plasma 6.8.0.
kgamma became redundant in the Wayland environment, as it relied on X11. Its successor, kgamma2, has now been integrated into Plasma Wayland.
It was Better Blur DX itself. And update was pushed. All is well.
