I made a free macOS App Store app that unlocks higher brightness (actually higher nits, not just a color filter). It works by forcing HDR content. I ve only tested it on my MacBook Pro 14 M5, but I assume it works on most modern macbooks.The description says The best screen poster , but it s meant to say The best screen booster (overly aggressive autocorrect in macOS probably).Youtube link to see how it works here:https://youtu.be/oQYE0r_UIzE
