You can get an LG (https://www.bestbuy.com/site/lg-65-class-un7000-series-led-4...) for $500, which has HDR. Did not compare these two side-by-side but generally HDR is what sells 4K TV: a small (<80") TV does not benefit from higher resolution, IMHO. HDR on the other hand, is a huge difference (and even on a regular SD signal a "smart" TV can usually blow up dynamic range with some image processing).
Any TCL or Hisense on sale is going to be better than Sceptre. Sceptres quality control is also horrendous, there was a time when one in three panels was shipping to me cracked. They make great ultra cheap monitors, but for the extra hundred or so bucks get a TCL.
