I was thinking the display could be "clearer" and it seemed to be "scuffed" in top right corner. I thought I would clean it… and then discover there was a "protective plastic film" covering it.
I easily pulled and removed it. The display is much clearer now!
I'm not sure if the covering is supposed to stay on, but like most things, it was probably placed there to protect unit during shipping.
The display does indeed look brighter now...
