The Lenovo Z50-75 has a faulty display

Question

Hello, I just got back today after picking up a Lenovo Z50-75 laptop. Just after starting it up I upgraded to Windows 10, while I was working. When it finished It started up with my own lock screen wallpaper and I noticed some colour banding issues. I figuired it was a driver problem, and needed to update. This was NOT the case. I was truly sad to see that this laptop suffers from a serious and even more importantly a KNOWN fault. Clearly the display is not accepting 32-bit color and this results in the color banding that was extremely evident on the display. Now the worst part is that Lenovo apprarently do not care about this issue, or for some reason think that tilting a display can affect the color bit, which is ridiculous. I want to make this as clear as possible. Lenovo have not just lost a customer for life, but being apart of the tech industry myself, I get asked a lot on which brand to choose, to which I will always tell people to avoid Lenovo. I should have done better research on this issue before purchasing, but i'm still treuly gobsmacked by Lenovo's repsonse and overall stance on this issue. You actually locked out the original thread about it as well. Your simply disgusting. The laptop has already been packaged up and goes back tomorrow, and like I said before, I will never buy a Lenovo product again, and not because I'm afraid of a fault, but because your support is clearly terrible and you don't make reliable prodcuts. At least not prodcuts your willing to stand by.

Okay, I have done some research on this issue. To be honest, it really got to me how something like this good happen in the first place.
Anyway.
Upon checking out some other color banding causes, I came across other users with HP laptops/tablest that had the exact same issue as described above.
The correlation here is that both devices use two froms of graphics, with an lower spec internal and a higher spec dedicated. Exactly like the above laptop.
It seems the graphics card did not enable dithered mode when signalling the 6-bits with the monitor, which uses this method for true color. A common technique for cheaper panels.
The point being is that this issues is nearly identical with too many correlations to ignore.
The HP laptop issue was solved with a bios update, which means it was a driver issue or technically a bios issue.
Does Lenovo care to comment on this. Since a different manufacturer had the same exact issue, and was able to fix it. It clearly shows that Lenovo were wrong, and really were trying ignore the fault.
