You aren't actually getting ANY more detail with downsampling. As others have said, downsampling is essentially the same as super sample anti aliasing. AA will make an image look "sharper" because the edges aren't as jaggy, but there is still the same amount of detail in the image. A 2560 x 1440 monitor gives you 70% more pixels, which means there is a noticeable increase in detail over a 1920 x 1080 display.
You can set your desktop icons to whatever size you want, even at 1080p. The icon size is tied to the resolution by default, but you can resize them for more real estate if you want.
