When I press Fn+f5 I get brightness at 95% and when I press Fn+f6 I get brightness at 100% but nothing in lower (or in between for that matter).
Just to clarify, do you want your screen to go below 95% brightness when you press Fn+F5? And that it is currently stuck at 95% only for those keys? If you manually change it from the KDE Power or Brightness Setting, how does pressing the keys behave?
For the latter part of your question, you wouldn't get anything between 95% and 100% from the keys alone, because the keys change in 5% increments by default.
