Monitor quality matters differently to different people. At work my employer gave me a Samsung panel and frankly I wind up looking more at the MacBook Pro Display than the big external display I have because the colour accuracy makes me want to vomit. I write code for a living so it's not even like colour should matter that much, but when I runt he app on the simulator on the external screen and everything is just off, or look at the Figma prototype the designers gave me or just tilt my head a bit too much and the shallow viewing angles completely shift everything - It's horrendous.
Now that monitor in general isn't that good, but I also look at supposedly good monitors and feel a little disgusted by Tham after a while, being used to my 5K iMac. - And I even have terrible eyesight. I could easily be happy with a lot of other monitors for programming work (I've looked quite a bit at Huawei's 28" MateView for example and think it could be good for code), but for my other hobbies; Video and photo work, it's a no-go
