Budget 4k TV's are not the same as high end models. They suck, they really do. I tried one out before I bought a $2,700 dollar 4k tv. The biggest difference is when watching movies, so much blur in the picture it's ridiculous.
Though, that was back in 2014, I haven't tried recent budget models. They may have improved a bit since.
Last year I went straight for the high end model, didn't bother with the budgets.
