Anyone have 4k TV and Xbox one S?

It's time to upgrade the TV and I have a budget between £400-650.
I'm after a 4k with hdr to make the most of the Xbox one S upscaling and 4k blu ray player.
I was looking at some LG but then I hear about motion blur and input lag.

I currently have a Toshiba regza HD and that's fine with no motion blur it lag so clearly i don't want to take a step backwards in those departments.

Just wondering if anyone uses an Xbox one S with 4k and can offer any first hand opinions.

Thanks.

I believe the LG problem is to do with the processing engine, disabling the engine or changing to a specific mode alleviates this I believe.

I'll check the article I was reading as I'm after a 4K LG w/ WebOS as it happens

I find it all a bit confusing and if I would notice these so called flaws that people pick up. I just read that the Samsung 6400 model in some reviews gets slated for motion blur. Why would a company produce a TV that has motion blur?
I've never noticed motion blur on my Toshiba- unless im just used to it?
The LG on offer at curry's at the mo apparently has a 10bit panel which is what you need as it's better than 8bit...which most mid range TVs use? yes is supposed to have terrible motion blur and input lag.
