Decided to bite the bullet after it went on sale again since March. Same price as before but I was able to chat with JB rep online and they brought the price down to $1609 for me and another $10 down after bundling with another item so extra $79 savings on top of the "$420 off" (nice)
Monitor has the new firmware, manufactured in Feb 2023. There's definitely some fan noise especially if your PC is water-cooled and a bit or weird flickering in certain HDR scenes, ABL is indeed somewhat aggressive for desktop HDR use but it absolutely lives up to its hype in terms of HDR1000, colours and just overall quality. Reviews cover everything I guess. Cyberpunk 2077 looks sick in HDR + RTX overdrive on these QD-OLEDs. The fringing is there but not too bad imo.
DWF is not on sale at this time so for $1600 this puts it as a cheaper option compared to it (and comes with gsync)
RGB software is very meh but not the worst I've used I guess.
P.S. This model also regularly goes on discount at the Dell outlet (refurbished though) for $1499 if you want to save another $100.
Obligatory Muzeeb mention.
