A blank canvas with room to crop
At 3840x2160 there are over eight million pixels to work with, which is the practical reason to take this size rather than a smaller one when the plain white wallpaper is going into a design tool. Crop a square out of it for a social post, or a 1920x1080 window for a video, and you are still at native resolution; nothing has been enlarged to get there.
As a base layer it also behaves predictably. A canvas set to transparent picks up whatever the application decides to show behind it, which changes between a preview, an export and another program. A layer filled with an actual white image is white everywhere, and stays white when the file moves.
What 3840x2160 actually covers
It covers a 4K monitor or television pixel for pixel, and it comfortably covers the high-density laptop screens that report a smaller size than they really have. A modern laptop panel renders at twice the resolution the interface is measured in, so a display described as 1512 points wide is drawing close to 3024 real pixels; a Full HD wallpaper is stretched on it, and this plain white wallpaper is not.
Display scaling on Windows works the same way for this purpose: setting the interface to 150 or 200 per cent changes the size of text and icons, not the number of pixels the wallpaper is drawn into. It is worth knowing which number your screen actually has rather than which one the settings panel shows you, because that is the one this plain white wallpaper is matched against. It does not cover everything, either. A 5K desktop display is wider still, at 5120 pixels across, and an ultrawide is a different shape rather than simply a bigger one; both enlarge this file to fit rather than meeting it pixel for pixel.
A plain white wallpaper as a working surface
A few uses want the screen itself to be white rather than merely to have a plain white wallpaper behind some windows. Annotation and whiteboard tools that draw straight onto the desktop need a clean surface underneath. Tutorial recordings made at 4K and delivered at a smaller size hold up better when the background carries no detail to lose in the downscale.
There is also a lighting trick worth knowing: a second monitor filled with a plain white wallpaper, turned toward you and dimmed to taste, is a soft fill light for a video call. At this resolution it fills a large panel without being scaled up, and the brightness slider becomes the only control you need.
