By all means a great TV, but if you're into 4K gaming at all then I'd say it won't be as good as the Samsung KS7000.
My (limited) understanding is that the Sony produces 8bit 4K picture and does some clever wizardry to upscale it to 10bit via software. Happy to be corrected on this, but I did find this out after a fair bit of research.
The Samsung KS7000 is full on, proper 10bit 4K.
It uses dithering.
Basically it manipulates the picture to emulate 10K. It's better than 8bit on it's own but not as good as 10bit.

"In a Dither
How can an 8-bit panel—or any other 8-bit step in the signal path—reproduce a 10-bit HDR image without banding? There are two main techniques to do this. One is spatial dithering, in which neighboring pixels are assigned color values in such a way that the banding is obscured. But this sometimes results in visible artifacts such as a checkerboard effect or what looks like noise, so it isn't used much in consumer TVs.
The other, more common technique is temporal dithering, often called frame-rate control (FRC). In this process, a pixel rapidly alternates between two colors to give the impression of a third color. Depending on the specific algorithm used, this can work much better than spatial dithering, but it can also result in visible artifacts such as twinkling, especially in dark areas. Still, this process works so well, it's even used in some professional monitors that are widely used in color grading.
In my recent article listing HDR-capable displays, one of the most heated discussions in the comments is about the native bit depth of the panel used in this or that model of TV. Unfortunately, some manufacturers, such as Samsung and Sony, do not officially reveal the bit depth of the panels in their HDR displays, saying that an 8-bit panel with good processing can perform better than a 10-bit panel with poor processing.
That may well be true, but I maintain that an 8-bit panel is an inherent bottleneck in the HDR signal chain, and compensating for it with dithering—even high-quality dithering—is not as desirable as using a 10-bit panel with good processing. Such a TV is generally more expensive to manufacture and purchase, but in my view, it's worth it to get the best possible HDR image."
There has been great discussion about this within the home cinema section, etc.
Basically the best TV to get right now is the KS7000 as it represents great value for money. It ticks every box and is a ridiculous price for what you get.
Unless you require wide viewing angles then opt for LG UH either 7 series or 8 series models as they use IPS screens with ultimate viewing angles.
If you have money to burn then it has to be an OLED panel as they are the best tv's you can get.
