Is there any change in the screen of the iMac 27 '2019 relative to the 2015 version?

After using the 2015 version for several years, the afterimages are particularly serious. I wonder if this is the case with the 2019 version? There is also the problem of gray spots, which is still not solved..
In addition, I have a timed script to switch dark-mode to prevent afterimages in the menu bar:
Timed Task
```
*/20 * * * * ~/. local/bin/dark.sh
```
# # # Script Content
` ` ` shell
#! /usr/bin/env bash
Osascript-e '
tell application id "com.apple.systemevents"
tell appearance preferences
if dark mode is true then
set dark mode to false
else
set dark mode to true
end if
end tell
end tell
'
```

Anonymous11545 Sep 13, 2019All displays on the subway will have afterimages... All displays on the Apple Store will also have afterimages on long-term displays... such as iPhone 7 and 8... Not to mention OLED, LCD will have afterimages for a long time. As for the issue of gray spots, I seem to have seen others complain on smzdm.com that the iMac Pro still has gray spots. I think 2019 … should …? It is recommended to buy AC +. I bought it for 20,000 yuan. It's really not worse than 1,000 yuan... I think most monitors should be the same, except that the iMac is all-in-one … a bit embarrassing … it can't be replaced if it's broken.

Anonymous358 Sep 13, 2019I have consulted many discussion materials at home and abroad about the gray spot problem. It should be a design problem. If the mold is not modified, the probability of problems after long-term use is still very high. When I passed by the Apple store, I went in to have a look. The iMac pro on the display stand is available and it is quite serious

Anonymous3645 Sep 14, 2019Does the poster's "afterimage" mean "burning screen"? I have this issue with my 2015 retina, but I have no similar situation with my other Dell U2311H monitor, which I bought in June 2011. I didn't pay special attention when using it. I think it's still the problem with this batch of panels. The scene of @ Anonymous11545 subway is quite special. The 24-hour picture is basically unchanged, so it is inevitable to burn the screen.

Anonymous3513 Sep 14, 2019The problem of screen burn-in is the same with the LG 5k monitor displayed in the Apple store. I left a window for a while, and when I opened it immediately, there were still traces of that window, which would disappear slowly.
