Pekorius Nedas, I did notice this in the Bug Description, however the sticker sometimes differ from what is originally posted in bug reports. Despite this, I'm having difficulties finding the Samsung support website for exactly:
300V5Z-S01EE

Would you have a URL handy I could reference?

Title:
  Samsung 300V5Z Backlight/Brightness controls

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Unable to change screen backlight level

   Brightness function keys work only from 100% to around 85% and back
  to 100%, looks like it only moves one step down. but brightness can be
  modified directly on display settings, so the bug is only on the
  function keys.
