Need Help Buying HDR10 TV

Long story short. I want to buy an hdr10 capable tv from Walmart. That's where I work. I have till Friday to hopefully find one at Walmart because I get an extra discount until Friday. My budget is 700. I currently have a vizio 55 4K 55d series on layaway which is not hdr10. If I can't find one in that range I'll just stick with the tv I got. Just looking for a little help. Thanks
