The warranty is accurate and it is indeed pixel perfect, my first unit had 6 dead pixels and I was sent a replacement when I contacted support. They even shipped out the replacement before I shipped out my original monitor, so never had to go without the monitor after originally receiving it. The replacement did have 1/3 of a single dead pixel (red led on one pixel doesn't work), however I can't notice it unless I try and no monitor will truly be perfect, even if you spend twice as much on a g-sync Ultra-Wide.
As far as customer support it was one of the best experiences I had with customer support (though ideally you wouldn't have to contact them, but things never work out perfectly), I never heard of a company shipping out a replacement before you sent back the defective unit. If I am being honest, I probably could of sent back my second panel too since it did have a single third of a dead pixel, but I didn't want to play the lottery again with panel quality and I was satisfied with the panel.
The only thing that you may notice about this panel and this holds true with other models using this VA panel is that there is some noticeable clouding. While the clouding is especially noticeable if the screen is black and I am in a dark room, in a well lit room it's not really that noticeable. Though I do have to stress this as some people may not be able to stand it, but in general I don't notice it unless I am looking at very dark content on the monitor and my room is not well lit. Honestly I prefer the clouding over back light bleed as it is less noticeable in comparison (at least to me).
From what I have read, people have issues with any gaming Ultra-Wide (it just depends on whether you can tolerate said issue), as IPS variants can suffer from IPS glow and back light bleed as well as a warmer screen on one side as well as coil wine and can have difficulty hitting the higher refresh rate of the claimed 100hz or 120hz. This panel on the other hand doesn't suffer from coil wine (at least not mine), hitting the claimed refresh rate, or back light bleed, just clouding. Also, while colors in theory are not as accurate as an IPS, if you truly need 99.9% accurate colors I don't think you should be looking at a gaming Ultra-Wide in the first place. So for me the improved contrast over the IPS variants makes images on this monitor look more realistic in comparison.
One last thing, Free Sync is buggy with this panel, and will result in some artifacts in games when enabled if you do not apply a fix (may elaborate in the future if others continue to suffer from this issue) each time you turn on the computer for Free Sync to work properly on all games. Though I did get this monitor in the first batch so this issue may have been completely resolved in subsequent drops. However if you have a Nvidia card this does not apply to you, though you may want to pick up a g-sync panel instead like the 120hz version from AOC for around $800, as that seems to have the same panel, so it may be the better option if you are on team green. If you don't care at all about adaptive refresh rates, I would say this is probably the best option out there for the price.
I may have dragged this on a bit too much, but I hope this helps even if it's 5 weeks late.
