If you can swallow the price, the answer is definitely yes. I have a room full of non-Apple monitors, including a pair of 4k's from LG and Samsung ("4.8 star, top rated, best in class,etc,etc") and beside the XDR, they look like a pair of flimsy screens from an Etch-a-Sketch. Not even close.
However, I also used an ancient Apple Thunderbolt display as a secondary monitor on my M1 Studio. In comparison, it looked fine, although in 2k only. When it died this year, I got a Studio Monitor, when side by side in my configuration, looks (from the front) exactly like a little brother of the XDR. And to my eyes, the quality of the image is the same. I almost bought another XDR, but it would have taken up too much space and since the secondary monitor is only used as a holder for reference windows, not really worth it.
My setup is for programming. I would not give up my XDR for its huge desktop and infinitely crisp text, but if circumstances required, I could be satisfied to use the Studio (or two of them) in its place.
