Ey? The displays are P3, by definition this means they are 10bit... Is HDR an industry standard? Can you give me an example of another laptop with this feature so I can see what a real 'best in class' laptop display looks like?
Do you feel misinformed?
The standard is called Ultra HD Premium.

Minimum resolution of 3,840 x 2,160 – This is the simple part as this is the resolution – the number of pixels that make up the TV's screen – of 4K/Ultra HD TVs. There can be no confusion here.
10-bit colour depth – This means that the TV must be able to receive and process a 10-bit colour signal, which refers to the number of colours a video signal contains. Blu-rays use 8-bit colour, which equates to just over 16 million individual colours.
10-bit colour, often called 'deep colour', contains over a billion colours. This doesn't mean the TV has to be able to display all those colours, only that it can process the signal. Most decent ones can, so there's no problem here.
Minimum of 90% of P3 colours – 'P3' is what's known as a 'colour space', a standard that defines the colour information in a video stream. Colour spaces exist to ensure that the picture you see at home looks right. Think of it as the language of colour in the same way English is a language with rules people agree on.
To qualify as an Ultra HD Premium TV, a TV must be able to display 90% of the colours defined by the P3 colour space. This number is what's referred to as the colour gamut, or the number of colours a display can actually handle. So, a TV that can show '90% of P3 colours' would be said to have a 90% colour gamut.
The higher the number, the richer and more accurate the colours on a TV.
This is a comparison of different colour spaces. sRGB / Rec. 709 is the standard for current TVs and it covers only 80% of the colours available using the DCI P3 colour space. (Image Credit:

Minimum dynamic range – If your head is hurting now then things are only getting worse from here on in. Sorry. To qualify, TVs have to meet a minimum standard for the maximum brightness they can reach and the lowest brightness – known as black level – they can achieve.
Sounds simple right? Wrong. That's because there are two different standards. They are:
OPTION 1: More than 1,000 nits peak brightness and less than 0.05nits black level
OPTION 2: More than 540 nits brightness and less than 0.0005 nits black level
The observant among you will notice that one demands higher peak brightness and accepts a higher (and therefore inferior) black level, while the other accepts a lower peak brightness but demands much lower (and therefore better) black level.
This is to accommodate the pros and cons of different TV technologies. LED TVs, which form the majority of TVs sold, support higher brightness but inferior black levels. OLED, meanwhile, can produce stunningly deep blacks, but aren't as bright.
In other words, the alliance has found a way to make everyone happy. Hurrah!
