You can repair only sensor dead pixels with "pixel-repair" function. These pixels are white or black. Display pixels can be coloured. And they cannot be repaired.

Display manufacturer assumes  till two single dead pixels in any display zone. We also assume two pixels in any zone. These two pixels are not warranty case for repair or replacement.

Three pixels and more on a display is a warranty case. It is necessary to distinguish between a pixels and a subpixel. We admit till 20  dead subpixels. They have less intensive glow in comparison with  dead pixel. The pixel glows brighter.
