HDR not available on external monitor

Hardware: MacBook Pro M1 2020, Samsung LU28R55 4K monitor, DisplayLink 4K Plug and Display Dock connected to my MacBook via USB-C.

Issue: when I plug my external monitor directly into my MacBook with a DisplayPort to USB-C cable, the HDR toggle appears as an option for the external monitor in System Settings > Display and I can watch videos, play games etc in HDR on my external monitor . However when I connect the external monitor with a DisplayPort cable to the DisplayLink dock, there is no HDR option/toggle in System Settings > Display and I cannot watch HDR video on the external monitor. I also tried using an HDMI 2.1 cable to connect the monitor to the dock to see ion that solved the issue, but it did not. Any suggestions on how to get HDR to work?
