Iris claims to perform brightness adjustments in software (GPU?), allowing the monitor’s PWM brightness to stay at 100%, for Win/Mac/Linux: https://iristech.co/iris/

I'm wondering if the Iris approach affects color accuracy, otherwise why wouldn't MS/Apple use the same technique?

The Iris approach lowers the device’s battery life, and the screen’s contrast ratio.
