For people that has scanlines on their G7/G9/Neo G9 and having difficulties to reach basic Samsung monitor support in their country, I was able to reach the Samsung HQ and got their answer: "Scanlines are because of the limitations of the screen". While Samsung HQ admitted it , there was some confusion with my support saying that some people may say that it is all the monitors that has this problem but my support said it is not all :
" when you search the internet for an problem about an product it will always look like it is an major issue and that every product has that issue.This is an distorted view. The reason this view is distorted is because we can see the full picture.Let 's take this case for example.You have scanlines on your monitor. Of course you think "Wait is this normal?"The next thing you do is you do an google search and here you find an 1000 post about people with the same problem.Of course all alarm bels will go of and you will think that every monitor has the same problem.how ever what you can not see is the amount of monitors that have been sold world wide and do not have that issue.If there were sold 1 million devices and of those 1 million 1.000 have an problem. it is still an amazing product. but the 999.000 people who have an great monitor with out issues.will not post about it. "
They ask me if I could give them the monitor to inspect that on their side and give a replacement but I refused because I don't know if it will be the same [also what is the point if Samsung HQ admitted it's due to limits of the screen]...
Later after I ended discussion with my support, Neo G9 got released : HDR issues, scanlines [again problems appear whenever they release a monitor] -> this proof that the example of situation that my support explained to me was totally wrong.
I have scanlines for these images, but maybe it will be different for you:

(Scanlines are more visible when refresh rate is at max (240 Hz))
Recently, I noticed that people are having scanlines issue with some colors (such as blue, orange, purple) but not on the entire screen anymore, maybe Samsung did their best to fix the issue as they said it was due to the limitations of the screen.

Pixel inversion issue on most of Odyssey G7 32" :
on pixel inversion tests paterns like lagom.nl : there are some spots (green/blue/red/white) where pixels are flikering. When moving the test pattern (moving the window), these spots do not change place. They only change place when modyfing settings of the monitor [sharpness/contrast/color/black equalizer] or color of image like Night Light on Windows.

I know that nobody would watch test pattern in their daily use of that monitor, but now that websites started to add dark mode , I started to notice pixels flikering on lines (reddit post/ youtube/google search bar or in LoL)
Scanlines i can forget since it only appear on specific image but seeing pixels flikering on my daily usage....

Update: new batches of Odyssey G7 32" use the updated panel in most cases
