I see most TV sets are 8 bit, some are 10 bit (8 bit + FRC) and 10 bit sets, so what difference is there between the 3?

If you put an 8 bit and 10 bit side by side playing from the same source, is it something that's going to be noticeable?

I was looking at the LG 49UH770V and the LG 55UH615V which are both 8 bit sets but there are over 150 UHD HDR sets to choose from..

I'm leaning towards the 55" as i have a 48" TV now.
 
Side by side from a high quality HDR source, yes you can easily tell the difference. In the real world the vast majority of people will never even know about the difference let alone notice it at home in a oddly lit living room, etc. not to mention there's not really that much decent content yet.

But saying that you might as well get the best you can for your money. But if your money is only £600-ish then the 55" LG is stunning.
 
just a shame TV's don't come with own calibration meter. If I was buying a new TV it'll probably be a OLED.

I've had a few LCD TV's but that was a couple of years ago. Pretty happy with them, once you watch HD then it's great. Not so great with SD though. Black levels pretty good, and pretty close to the Pioneer plasma got now.

I would go for 10 bit panel.

I'm not sure what panel was in the Samsung plasma, but it did something funny with graduation.
 
A physically viewable benefit that occurs from it but is rare to see nowadays as Blu-Rays etc tend to be mastered within the limits of the source is sometimes in a scene with a big dust cloud or something similar, with different colour shading throughout you can sometimes see slight blocky lines seperating various shades rather than a completely smooth transition. It's few and far between nowadays but 10bit allows for those extra few colours in between to allow the smooth transition.
