The block test isolated the issue down to a display image burn. This is when a the given pixel or group of pixels have been over biased so the in-plane switching which controls the color is unable to enable the correct value to set the color correctly.

The block test isolated the issue down to a display image burn. This is when a the given pixel or group of pixels have been over biased so the in-plane switching (IPS) which controls the color of the given pixel is unable to enable the correct value to set the color correctly.
There is very little you can do to undo the damage. You might be able to force the IPS logic to fix its self by over saturation of the complimentary color within the given space. Basically we need a negative image of the same image to burn the display given pixels.
The only other option is replacing the full display assembly or the raw LCD panel. While not cheap these are very nice displays and still highly sought!

I have two my self, I would hate to try to replace them as I find most displays are not as nice as these, just perfection! If Apple where to come out with a 5K 32” or larger version with the same ports I would buy it! But as we know Apple won’t be doing that ;-{
