I tried it for a while, it was fun explaining it to people, but didn’t actually help much. I ended up blocking all time wasters except HN, which is almost monochrome anyway.

I set grayscale in my phone's quiet hours settings. It's to help me sleep, rather than to reduce my phone usage. It means if I wake in the night and look at my phone, I'm not blasted by colors. Or if I stay up a bit later than usual. I find it beneficial although probably not revolutionary.

I did try setting my phone to grayscale during the day but didn't see much if any benefits there.

This was my experience as well. While it is less straining on the eyes, that was the only benefit I saw. I didn't see a reduction in screen time or less anxiety about notifications.
