Any image that is static can, over time, leave traces or temporary artifacts on the panel.
If left long enough, they can be permanent. However, with the technology available today, it's pretty difficult to do - but it CAN be done.
If you can, during gameplay, lower the brightness so that any static images don't etch into the screen.
Most people will probably not have a problem with permanent etching, however, if that's all you do and the same image is up on the screen every day, it is possible.
Thanks for your interest in Samsung products.
