I'm sceptical that it would be all that good an immersion, especially if you've at least once used a VR headset.
It's one of those uncanny gaps, that tend to actually widen as you believe you're getting closer.
It might work somewhat better with racing or space simulators, where your view is strictly forward, but I've tried flight simulators for the longest time with screens (actually since V1 on the Apple ][) and that just doesn't work for me at all: not on my big 42" 4k nor on a curved wide 3k 32" OLED ony of my sons owns, including with Tobii's eye tracker.
My son loves his curved screen, but perhaps that's because he is really constantly on the run and nearly all action is forward. I'm typically killed by the time I got my bearings in modern games, but until then I try to get oriented and that's where I yearn for VR, even if the headsets are a bother (HP Reverb Pro currently, Oculus DK1/DK2/CV1 before).
And I'm not sure I'd tolerate a curved screen for work. I've tried that virtually via Xreal, but the quality of that was too bad to get a really good impression.
I'd really have to try it first, but with these big monitors even if you get a free return, the sheer physical hassle of dealing with such a monster, makes that near impractical. Flat 42" screen were already marginal, when I had to return a broken one and couldn't just get a pick-up service.
And you really need to experience this with your games and your gaming hardware to know how your brain will accept or refuse to be immersed.
And if it's worth the non-trivial expense.
