It has HDR10 (the standard of which 10 bit is a part)

He asked whether it's a 10-bit panel though, which doesn't have much to do with HDR.
The extra bit depth in HDR content is used for a wider brightness range, which is reproduced by a backlight that's adjustable in sections ('local dimming').
The brightness range of an LCD panel is defined by it's contrast ratio, the bit depth of the panel doesn't change that but only makes the steps between different brightness levels smaller. If they're too big you notice an effect called banding.
It's one of those refinements that only make a small difference to picture quality and is consequently only found on higher end TVs.
This does technically have local dimming in 55", but the implementation seems to be so crude it's not any better in practice at displaying HDR content than competing TVs without it.
HDR10 is a format for specifying what a picture looks like, it says nothing about the TV's ability to reproduce that picture. Even the best TVs on the market are still a long way short of being able to display the full colour and brightness ranges that can be specified in HDR10.

And you're talking about brightness, local dimming and contrast ratio, all of which have nothing to do with 10 bit colour...

Um, what? How can brightness have nothing to do with colour. How do you think colours are created?

Your post was gibberish and your understanding is limited.

I't's hard to take your criticism seriously if you simply state I'm wrong without even attempting to explain why.
They perform very similarly, why shouldn't they charge a similar amount?
These are mid-range TVs, many components have been downgraded from the best that they could have fitted. I don't see why it's a big deal that LG have chosen to do so in this particular area rather than in the same areas their competitors have.
It doesn't have an unduly large effect on picture quality. For normal TV use the only area it seems to impact is colours and there are plenty of other things that can cause similar behaviour. Hisense's current flagship suffers from a similar problem through other causes, as will other TVs.

Well RGBW panels are cheaper to produce and give less quality picture in a whole, so that's why they should charge less ... Not a huge amount , but there should be a noticeable decrease.
And the Hisense are lesser panels, but they are a lot cheaper than the 'better' brands

They do, the cheapest 55" model in their range that doesn't use the technology is the £980 SJ850. I'd say £400 was reasonably noticeable, although of course that includes downgrades in many other aspects too, many of which will also have minor impacts on the picture quality of the TV.
That's the point, it's just one design choice among many. You have to judge based on the resulting picture quality, not the fact that it exists.
The Hisense NU9700 is £3,000 in 70". LG's most expensive 'RGBW' model is the larger 75" UJ675 which goes for £2,200.

Think Il wait a year till 4k oled are a bit cheaper with hdr plus
This deal has ended but I bought it for £585 in Argos (one of the lucky ones who had the 10% off codes)
It a lot better TV than the LG for £6. I'm sure it'll be on sale in black Friday too.
Either that or the Samsung ue49mu6220 or similar ue49mu6400 are all better TVs that will be similar price ranges.
LG used to be good , still are at the oled ranges but they screwed up bringing out RGBW panels and not telling anyone, then charging a similar price for them as the RGB tv's.

Also you could get the 55UJ634V model from Argos for £599.

I'd think that a better deal at £599.

That's my opinion anyway.
