There are thin strips on the left and right side of the screen, about 5 pixels wide, which are darker than the rest of the screen. It looks like a shadow from the bezel (obviously not). The left side is far more pronounced. Flaw?
I'm not quite sure, but there appears to be a slight nonuniformity to the backlight. I notice it when panning vertically, it gives the impression of a very faint shadow on the moving image. Flaw?
Flashlighting is part of LCD/LED tech especially edge-lit.
The extra tension on the corners effect the liquid crystals' movement/closing.
Try lowering the backlight or use eco sensor.
The side strips are because of the ultra-thin bezel, it used to be worse on the D and ES series.
They are barely noticeable- only on brighter solid screens.
The shadow is known as banding- noticeable on solid color screens.
Its due to uneven light spreading from one side of the screen to the other- edge lighting.
