Are you asking if you should install it? You're fortunate to have a shiny and new enough tablet to get frequent updates (including security updates). My older, cheaper tablet was only getting them quarterly but now (as its just gone 2 years old), it'll only get updates 'if Samsung deems them to be needed'. I've only found a problem with one firmware update that Samsung released for my tablet and in fairness it wasnt a showstopper and they released another update soon after which addressed the problem so I'd say installing the update is unlikely to throw a spanner in the works on a basically setup device.
Sorry that questionmark at the end of your initial sentence indicated to me there was something you were unsure of - the written equivalent to some Australian and American people raising their intonation at the end of a sentence.
Although you will get a notification when an update is available (which displays the updates details), its possible to then not go ahead and install it.
If you're wanting feedback from others who've installed it as to what they think of it, it might be worth letting us know what you think of it and if you have noticed any differences.
