The most I get on my gaming tablet Galaxy Tab S3 is minor and very temporary burn in when playing GTA San Andreas or a similar game with bright buttons/indicators on the screen. It usually shows slight imprints (that go away quickly) when switch into the music player (which has a gray background since most of my music doesn't have album art). Nothing permanent. What you really should worry about is that, if you are planning to use your device for more than 3-4 years, is that you may end up with a slight green tint (people have warned people considering a purchase of a used Galaxy Note 3). Maybe the reason that I don't experience permanent burn-in is that I am not a gaming addict, and hence I get saturated after 1-2 hours of gaming...
