Las primeras reviews del K8500 mencionan algo sobre este tema:

After testing the K8500 with a few of the initial 4K Blu-ray discs, all of which offer HDR, one thing is clear. If you want to extract the maximum benefit out of this player, you need a high-end HDR-capable TV. When viewed on standard, non-HDR 4K TVs, the discs we tested don't offer any substantial picture quality improvements over standard 1080p Blu-ray discs.

But not every HDR TV is created equal. Our viewing sessions with some of the best sets available today -- LG's 65EF9500 and Samsung's UN65JS9500, both exceedingly expensive -- showed the full impact and realism of HDR, leaving standard Blu-ray in the dust and leaving us hungry for more.

On the other hand, cheaper HDR-capable TVs -- such as myriad midrange models due later this year -- probably won't show as much of an advantage. We weren't able to test any such sets directly with 4K Blu-ray yet, but our previous tests with models such as Samsung's JS8500, one of the cheapest current HDR TVs, aren't encouraging. Then again, maybe with some discs and newer HDR-capable TVs there will be a substantial improvement. We'll have to wait to test the 2016 crop of HDR TVs to know for sure.

Es decir, para estos críticos sólo se puede experimentar de verdad el HDR con los mejores televisores del 2015, o comprando gama 2016.

No sé hasta donde esto será exactamente así, o no. Personalmente tengo la sensación que en la JS8500, sí debe quedar resultón el HDR, pero estas son las informaciones que tenemos hasta ahora.
