2021 NEO QLED issues with vertical lines / bars (vertical banding / Jailbars). 2 panel replacements without success

[one87]

QN95A Neo QLED 4K HDR Smart TV (2021)  After 2 nerve wracking repairs and long waiting times I decided to post in here. The first repair was due to a yellowish cloudy spot on the screen. After that my TV came back with a new issue: There are around 13 vertical bars and depending on the color settings/conditions they are clearly visible. So I filed another complaint which led to a second replacement of the panel, the vertical bars are still there. 

Today I got a call from Samsung and they promised a credit note since the TV was in repair already 2 times. Furthermore the lady explained that a Samsung technician checked my pictures stating it looks "as per specifications". 

So speaking for myself as a hardcore Samsung fan, owning nearly everything of their product line for many years (incl. TV's), I never experienced something like this. I also can't accept that this is the "standard" for the 2021 neo qled lineup, especially looking at my pictures attached where you can clearly see a difference. While investigating about this, I came across tons of reviews of many neo qled owners describing exactly this issue, but no statement from Samsung. 

Appreciate any comments from the community and/or Samsung to clear this up. I think for a TV in this price range we can expect a perfect quality as advertised.

Do you see the banding when watching tv if you do it faulty plain and simple and demand a engineer visit don't go off of the phone until you get on logged

I can see only one horizontal white line in the bottom TV display along the entire length (last row of pixels).

Go onto YouTube and search and then run 5% grey uniformity test and if the line you see is not meant to be there it shows up .
Beware once a fault is seen you can un see it

Samsung don't make there own panels anymore I am now on my 3rd tv in a year .
Buy poor panels making a poor Samsung

I have this problem on my 65” and am a little concerned that Samsung see this as normal! I shall be contacting them to say it is very much NOT normal, nor acceptable.
