In short
LG OLED dead pixels at the edge often means dark/dead cells or edge artefacts — panel ageing / panel, not the same as logo burn-in.
Unlike burn-in & pixel care: burn-in = ghost logos; edge dead pixels = failed cells/edge.
Not the same as burn-in
Pixel refresher targets image retention / burn-in. It usually does not fix dead cells at the edge. See also vertical line.
Why not a power supply board swap
A power supply board swap does not fix panel edge faults. Document (photo), model, warranty/panel diagnosis — AmparioWeb focuses on power boards but helps triage.
What you can do
Photo on full-screen grey/white, note model, check warranty, do not expect miracle pixel-fix apps.
