Does the Gigabyte M27Q rev2 really support HBR3 on DP 1.2?

Hi I am looking at the Gigabyte M27Q rev2  (https://www.gigabyte.com/Monitor/M27Q-rev-20/sp#sp)   and I have a question:

The spec sheet says it has a DisplayPort 1.2 but also claims the monitor supports HBR3 which was introduced with DP 1.3   https://en.wikipedia.org/wiki/DisplayPort#Specifications.

The Supported Timing List in the manual only shows support for HBR2 resolutions and framerates without specifying color depth 8 or 10bit.

So in 10bit mode, is the monitor limited to 1440p 120Hz and 4K60 (downscaled signal) ?   Or can it support HBR3 resolutions and framerates (e.g.:  10bit  1440p 170Hz and 4K60Hz+) ?


Tldr: does the monitor really support HBR3 resolutions and framerates on a DP 1.2?
