But - from your photos - it also appears a bit Darker (more visible) than on our set, whose shadow was really visible ONLY on a couple of solid gray slides.
As noted earlier, this Glitch seems to have "completely" disappeared on our panel (I cannot see it, so therefore assume it IS gone...).
If you haven't done so already (and perhaps even if you HAVE), would try running Slides / Other Full-Screen Content (like Animation) for 12 - 18 hours / day, for a number of days in a row.
NOTE: No reason why you cannot do this IN ADDITION TO whatever "normal programming" you like to view (!) - instead of turning the TV "OFF" when your show is compete, toss in a SD card with slides, or put some other full-screen programming on - using Aspect or Zoom controls to ensure logos, streaming tickers, etc get safely moved off-screen.
That is a shot in the dark, but it DOES largely replicate our "new panel aging routine" - and for SOME reason, our panel has "self-corrected."
