I can't even find a datasheet on that chip, so it's hard to say if it can be programmed to do what's needed.The Benq XL2730Z uses a realtek 2796B scaler, so your protocol should also work on this monitor.
But would this work with variable refresh rate that can change every millisecond?

But if you incorrectly estimate the current frame time, you could compensate for errors in duty cycle value for this frame at the next frame, and carry the remained forward that way, to achieve that fixed percentage which would keep the brightness uniform over time.
