Actually if you just bought a 4K TV it should do the upscaling for you. If you have a 4K TV you might want to wait on buying the blurry player because supposedly a true 4K DVD player will be coming out at the end of this yearI saw a Samsung Bluray player that says "upscaling 4K".
I'll need to look into more about what exactly that means. I know what upscaling is. Just.... need to learn more. It was I think $189.
For now I'll just be happy with what a beautiful picture I've got with the content available
