I bought a Sony bravia 65XE900E recently. For a LED TV the HDR is really good, especially considering the price. Got a good deal on it in the UK. I paid £1545, but got a free 4k film with it and £200 cashback.
One of the best thing is it has Chromecast built in so I can throw stuff from my phone across including showbox.
4k games look amazing and HDR is really impressive. Price should be coming down for this TV as a newer model is about to release.
