I have used my galaxy book 12 to test this utility, no error reported, but I can't see any difference after I changed pwm freq from 300hz to 20000hz. I used my phone's camera to test.

I test in Thinkpad t460s.And the default freq is 200,and I can obvious see the fresh line in the mobile camera.But if I change to 2000,the fresh line disappear.So I think it work for my laptop.

AMOLED display have a totally different mechanism than traditional IPS panel. If it didn't work for you, I highly doubt you can do anything to it. The PWM freq is either managed by or even hardcoded into the firmware of screen driver borad. Even the latest phone don't have that high PWM frequency.
