Odds are any replacement panel will have one or two dead pixels as well
That's just how it goes with the current state of panel production at the current resolutions.
Unless you're willing to pay out for a reference-quality panel, this is just something you have to live with.
Occasionally you'll find a consumer panel that IS perfectly flawless, but you can't count on it when buying a monitor.
My 43" 4k has 4 dead pixels across the entire panel, my 27" 1440p 144hz has 2 dead pixels.
most people don't even realize they have dead/stuck pixels since a single pixel on a modern high PPI display is fairly difficult to see without searching for it.
