Curious if I can "trick" to OS into thinking everything is HDR or something. Or maybe some code I can enter to adjust the brightness?
 
Why would you do that? It would be bad for your eyes, use more energy and on SDR content the whites and light colours would be blown out. You'd see less detail and less colour accuracy on such material.

Peak HDR brightness should only come on in the areas of an image or a video that have been specifically graded for it.

Any proof that "Bright displays" are bad for people's eyes? Seems like an old wive's tale and Urban Myth.

You're confusing the old wive's tale 'Don't sit next to the TV your eyes will go bad' with something else. We're not talking about a generic term 'Bright displays'. We're talking about the higher levels of brightness of HDR which are unsuitable for general use in normal reading conditions, although can sometimes be useful if direct sunlight is falling on your screen.

Mind, that old wive's tale isn't completely wrong. It depended on how long a person sat in front of a screen to cause eye fatigue and strain. The idea began because kids were being hooked on staying in front of the television too long, not because of the distance of the television.

When we're talking about computers then that time is almost all day for a lot of people.

I personally set the new XDR displays to 400 nits for comfortable indoor use. My Eizo is set to 120 nits/candelas for work which is the general rule for video editors and colourists.

Go and stare at the sun for a while. Of course bright lights are bad for your eyes that’s why your pupil shrinks down as far as it can and you squint in bright light to protect your retinas!! I am in awe that you can’t work this out for yourself. HDR level brightness is for the highlights in video not for working on a white screen with, for exactly this reason.
 
Agreed! I bet this is possible though. Apple could do it but battery life would be terrible.
My 14" can't even get to 500 nits. Would love to know if there was a way to manipulate the brightness besides what Apple has included. My system can only reach about 70-80% of brightness, and yes all the auto dimming functions are off. Sad thing is you can't ultimately force a reset of the NVRAM at the moment on the M1 Macs.
