My screen is flickering bright green color on low brightness?

[Android Central Question]

I have a 2 years old Samsung Galaxy S9 plus.
Sometimes, when I lower the brightness of my phone or the brightness goes down on low light conditions as Adaptive Display is 'ON', a bright green color keeps flickering. If I increase the brightness again, it will go.
I did whatever the internet told me to do. I factory reset the phone, enabled the 'Disable HW Overlays' in Developer Options etc. Nothing solved the problem.
This happens only very rarely. Most of the times, my phone will be fine. Very rarely, the flickering occurs.
I took it to the nearest Samsung service center and they told me that i may have to change my phone display. It costs around Rs. 19000.
My question is, if it is a display problem, why it happens very rarely? I want to make absolutely sure that this is a display problem before replacing the display.
Will this cause because of any other issue?

I recently have seen a post about this and it appears to be due to a recent update. I couldn't get a grip on how wide spread the issue is, does everyone have it, do only a few have it, but it seems to be not only a known issue by users but by Samsung as well. So far it's unclear what they are doing about it.
