Does XR343CKP support Display Stream Compression through USB-C DisplayPort Alt Mode?

I have this monitor.

According to specs it is capable of 3440x1440@180Hz through USB-C Alt mode.
But when connecting MacBook Pro the maximum is 100Hz, and when changing the upstream USB (on the same cable) from 2.0 to 3.0 the max refresh rate is 60Hz.

I read that USB 3.1 gen 2 can take 2 of the 4 steam lines in USB-C cable and that in order to achieve higher framerate on just to lines Display Stream Compression is needed.

Does this monitor support it?
