You can clearly see that it's getting worse by increasing the refresh rate (no **** Sherlock). But IMO it looks more than acceptable in 144hz mode.

Holy crap! So counting in what Malinkadink wrote, I am assuming the bottom right corner backlight issue is a general production error.
Well, I never ran it at lower frequencies (at least not while checking on the backlight) so I could not say.
Also, as an update, I received the display from RMA today, but they did not repair it, there was a repair report included in the package that said that non-perfect backlight uniformity was a common production error that was not covered by warranty. I think they did not understand what exactly the issue with my XB241H was, because all I had told them was that there was bad backlight uniformity, but I had not illustrated how bad it really was.
I then contacted them again and also sent pictures, I also called someone from Acer tech support who, looking at the pictures, told me that if the backlight uniformity is so extremely bad that that would have to be repaired and he then created a new RMA ticket for me. So, I will send the monitor back to the Acer repair center tomorrow.
The better 5m cable did work at with FHD 180Hz without problems.
Also, a question to anyone who knows about monitor repair: If the Acer XB241H was to actually be repaired and not exchanged, would the panel-part be exchanged? Does the panel-part also include the backlight?
