Having been working on it last few days can add some more details for productivity. It is pretty great in terms of real estate to work with, amazing in fact and I love it, used to it already size wise. Do a dual hat role of Project Manager / Consultant, so lots of plans, finance documents E-mails open etc rather then programming. For that reason snapping E-mails to one part / teams to another etc leaves a nice big section for my main projects / documents etc which works real nice. PPI already covered, find it sharp enough to use. For Scaling 125% is fine, but day in day out, have settled on 150% and find that works really well for me.
In terms of text, from distance I sit, 70cm - 80cm away from eye's to screen, no I cannot take it all in at once clearly. I can focus clearly on about 2/3 of the screen at once then eyes move around as needed. However for me, that is largely okay as what I can see is my primary documents I am working on while the bits outside my direct vision is my mailbox and the like. If it was curved, then I think it would help to bring things into the periphery most certainly. Also have a 34" ultrawide which is almost as wide and there the edges coming in do help vs it being entirely flat.
The glossy aspect is a funny one, reflections are visible no doubt about it, however once I am going in terms of use, largely filter out the reflections. In terms of the room, for a few hours a day, there is a lot of sun lighting up area behind me, at that time can get decent amount of reflections, but tweaking the blinds makes it a non-issue. I think it is going to be down to how much you can filter it out and if you can control the light in the room.
Last comment is ABL is there. You will notice it if you have a large white document and as you open it up light will decrease, more so after it covering 70% or so of the monitor. In actual use, its actually not too bad dimming the brightness slightly from having a large white document open which can be intense so for me actually works out okay.
TLDR, working pretty nice for work and gaming alike. Even streaming apps like netflix 4k look very nice vs my big OLED, partly down to the PPI I expect being much higher so things do look very good. Factors that will need to be weighed is if you can control room lighting at times, distance of monitor to eyes will dictate how much you can take in one go etc.
