Does the M1 iMac have built-in HDR 10-bit display/panel?

Does the new M1 iMac have built-in HDR 10-bit display/panel? I read that the M1 Apple Silicon supports HDR 10-bit output with at least macOS Catalina installed, but I can't find any specifications that explicitly say that the new M1 iMac built-in display/panel is a true HDR 10-bit one. I read on the forums that the older iMacs' display are not true 10-bit, but 8-bit + FRC.

Also, I can't find any other specs about the M1 iMac's display such as contrast ratio, peak brightness. The Apple Pro Display XDR is said to have up to 1600 nits of brightness and 1,000,000:1 contrast ratio. Other Apple devices like the MacBook Pro 16" and iPhone 12 are known to have 500 nits brightness and over 1000:1 contrast ratio.

Anyone gotten their M1 iMac and managed to do testing on the display for brightness, contrast ratio, and/or other specifications?

Nope. Even the panel on the new 12.9 iPad is 8 bit. The M1 can support HDR in it has a wider color gamut but it cannot support it in terms of peak brightness etc.

The iMac is rated for 500 nits brightness. It does fine in my office with a single window to the northwest.

He says yes it does support 10 bit per channel with external monitor with mac mini so I guess it does with iMac too.
