Oh you brainlet, have you never heard of Sony's policy?
Nor will apple replace 1 dead pixel, can try your luck but it's close to none.
Nor will Samsung
In fact almost all of them use ISO 9241-307 classification for dead pixels, these are per million pixels
 
|  |  |  |  |  | 
| 0 | 0 | 0 | 0 | 0 | 
| 1 | 1 | 1 | 1-2 | 1-5 | 
| 2 | 2 | 2 | 1-5 | 1-10 | 
| 3 | 5 | 15 | up to 50 | up to 50 | 
| 4 | 50 | 150 | up to 500 | up to 500 |

You will almost never find a class 0 panel unless it's reference monitor or some very expensive product. Most consumer panels are in class 2.
Some companies vary from this chart for warranty but rarely. It can literally depend on the mood of the support tech but they can always fallback to this chart and you have nothing really.
You're trying so hard yet miss the target completely with basic knowledge, it's really pathetic sad trolling at this point.
