On desktops/laptops, 1366x768 is still by far the most common resolution.

SVG or not, but on a 13" - 15" 1366x768 screens icons need to be pixel-perfect or they will look crap.

If you have a 1366x768 screen why would you need DPI scaling? You shouldn't be affected by this issue at all if your resolution is below a certain threshold.
