I use DELL U2720Q which corresponds HDR and MacBook Pro(2019, 15').
Although I don't know whether its cause is by ddcctl, the monitor brightness isn't changed when HDR option is enabled.

By the way, my environment details is like below.

Model: MacBook Pro 2019, 15-inch
CPU: Core i9-9880H, 8-core 2.3 GHz
RAM: 16GB
GPU: Radeon Pro 560X, 4GB VRAM

Monitor: DELL U2720Q

I use USB-C to output to U2720Q.
