SUMMARY
When you have dynamic wallpapers (day/night wallpapers) and use slideshow as your wallpaper type, they will never change. (for me they are always stuck in the night picture)
I tried the dropdown to switch dynamic wallpapers based on plasma style, day/niight cycle, or always light/ dark, but they don't appear to have any function and you cannot apply after changing this setting like you can in the image wallpaper type.

STEPS TO REPRODUCE
1.  Go to System settings
2.  Go to Wallpaper
3.  Set Wallpaper to 'Slideshow'
4. untick boxes so that only day/night wallpapers show

OBSERVED RESULT
- the wallpaper is just not changing at all

EXPECTED RESULT
- wallpaper would change from day/night based on either the current date/time, plasma colour, or manually setting to day/night
