HDR monitors = 10 bits monitors?

I am little confuse on this one, there is so many HDR minitor/TV comming out.
Especially after Apple announced the XDR monitor, I am seeing people compare it with the Sony 10bits monitor pricing.

I though HDR monitors just 8 bits with 1000+ nits and using a diferences profile than the traditional rec709?
Am I wrong? or the HDR means they are 10 bits monitor?
 
For an HDR monitor you need:

- More than 8-bit resolution
- A native (not dynamic) contrast ratio of more than 20,000:1
- A monitor that provides a wider color space than Rec.709
- Have a maximum brightness of over 1000 nits (although OLEDs are the exception because the blacks are truly zero)

Having 10-bit panels is not a technical hurdle, they are just more expensive.
Having a contrast ratio of over 20,000:1 is difficult unless the monitor is less bright, this is the case for OLED panels.

For other panel types like IPS (VA panels have a higher contrast but have a much narrower angle of view), tricks have to be used to get a higher contrast ratio, none of those solutions are very satisfactory, an economic break-through technology is still not out.

One myth is that HDR simply means brighter. The average brightness of an SDR and HDR video should not differ much, the HDR average brightness being only slightly brighter.
It's the dynamic range (blacker blacks and whiter whites) that makes the real difference.

I’ve seen the contrast ratio on some OLED panels, depending on manufacturer, listed as 1,000,000:1 and Infinite, since the pixel can actually be true black(emmiting zero light).

Right but OLED is problematic because of burn-in, long-term reliability and the lack of brightness.

Professional HDR monitor brands like FSI, Sony and Panasonic start moving away from OLED.
 
Personally I haven’t had any issues with burn-in on any of my professional OLED displays/VF’s(4 monitors, 2 VF’s) or my TV in the bedroom. Brightness also isn’t an issue in normal viewing circumstances(i.e: not outside in noon daylight). My LG OLED in the bedroom is HDR 10 and DolbyVision. Sony’s uber expensive reference grading monitors are OLED.
