How can I ensure that my Windows 10 system displays colors in 10-bit?

Hi Guys.

On Mac OS Monterey looks like 10bit works. But when i got to Windows 10 which was installed by bootcamp looks like os is in 8bit.

I cheaked all possible setthing in Windows and awrything is set to 10 bit and Windows says i am 10 bit.

I use this test file: https://raw.githubusercontent.com/jursonovicst/gradient/master/test_sequences/1920x1080/gradient_1920-1080_25-50.png

On Mac OS awrything goes according to description and i have 10bit. While in Windows i have 8 bit color.

What is qwrong?
