Night Color not working until color temperature is changed

I have night color set to always on, but after booting, night color is not active. Opening night color on systems settings and adjusting the temperature slider to a different value and clicking apply causes night color to activate. This has been occurring on both Kubuntu and Fedora KDE for months.

Operating System: Kubuntu 22.04
KDE Plasma Version: 5.24.7
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
Kernel Version: 5.19.0-41-generic (64-bit)
Graphics Platform: X11
Operating System: Fedora Linux 37
KDE Plasma Version: 5.27.2
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.1.18-200.fc37.x86_64 (64-bit)
Graphics Platform: X11

Looks like a bug, please report it at
