Has 4k laptops like the Lenovo Y50 gotten better in scaling and such in 2015?

4K laptops have been out for a while now, and I was wondering if scaling and all those other issues have gotten better with Windows 10 and all the current new updates? I'm using an Nvidia 860 4GB, 16GB RAM and 1TB SSD.

I know everything used to be super small and unusable on the 15inch 4K screens, but has it gotten better now?

Windows has a scaling setting. You don't have to keep it small.
