So many things that are not in favor of this monitor, which IMHO is too little, too late and uses 'last-gen' technologies. Where are the OLED HDR G-Sync 165-200Hz monitors of the same or even higher resolutions? And the 16:9 aspect ratio is already losing market share quickly to the 21:9 monitors as more and more people transition over. This monitor is just old news being sold as something new.
...G-Sync also has a much better lower dynamic refresh threshold of 30Hz versus 48Hz of the FreeSync 2.
The last I checked, OLED still wasn't really suitable for screens that will be left on for many hours a day. The problem is that OLED degrades relatively quickly. If an OLED screen is left on for 8 hours a day, it can lose around 50% of its brightness after just 5 years, with blue degrading faster than the other colors, potentially resulting in the color balance getting shifted over time. TV and phone screens are typically only on for a few hours or less a day, so that might not be as much of a problem for them, but many computer screens tend to be left on for much longer lengths of time.
And this screen shouldn't need G-Sync, since it has the industry standard Adaptive-Sync, otherwise known as FreeSync. Complain to Nvidia for why they still only support their proprietary version of the technology, while refusing to support the open standard that's part of the official DisplayPort specification. Microsoft announced just the other day that the Xbox One will be getting Freesync support soon, and it probably won't be long before the Playstation adds it as well. Screen manufacturers need to buy an extra, expensive chipset from Nvidia to support G-Sync, whereas FreeSync is supported by standard DisplayPort hardware and doesn't cost extra to add. Nvidia needs to support the open standard that everyone else is using, not the other way around. It seems likely that Nvidia may add support for FreeSync eventually, and there's not likely any reason why they couldn't enable it for their cards today, but they are holding out as long as they can to sell overpriced monitor chipsets and encourage people to stay locked into their hardware ecosystem.
And as for the "lower dynamic refresh threshhold", that's not entirely accurate, since Low Framerate Compensation (LFC) allows Freesync to continue operating at lower frame rates. Below 48fps, it will simply keep the same image up for additional frames at a higher refresh rate. For example, at 47fps, it might display the image twice at 94Hz, and at 30fps, it might display the image twice at 60Hz to keep adaptive sync active at frame rates below what the hardware natively supports.
The resolution and frame rate seem great for this monitor. High refresh rates are good to have, but you start seeing diminishing returns past a certain point. I doubt anyone could notice any significant difference between gaming at 144Hz and at 165 Hz. And 144Hz is already pushing the limits of what VA and IPS panels are capable of. At higher refresh rates than that, you're pretty much stuck with outdated TN panel technology, which aside from having faster pixel response times, is worse than the other screen technologies when it comes to actual image quality. And that's assuming your CPU can even keep up with frame rates in excess of 144Hz, which won't be the case in most recent demanding titles, even with the highest end CPUs currently available.
2560x1440 is also a good resolution, and 31.5" is a decent size for that. Higher resolutions will be harder to push at high frame rates in recent games, even on enthusiast-level cards. And if someone really wants to run their game at a 21:9 aspect ratio, there's no reason why they can't on a 2560x1440 screen. Setting the resolution to 2560x1080 on this screen with a bit of letterboxing at the top and bottom should result in an area equivalent in size to a 30" 21:9 monitor.
