1600 brightness with VIVID & BetterDisplay

Hello, I faced a very unpleasant problem earlier on the previous OS, I could watch HDR movies and videos both through the browser and through iina with VIVID or betterdisplay brightness turned on, which allows you to turn on 1600 nits of brightness, I turned on one of these programs and turned on the movie, there were strong overlights on white, nothing was visible at one point, I noticed that when switching to another desktop, the color somehow changes, something happens to the screen and when returning to the movie or video on the previous desktop, the overflow disappeared and the HDR effect was just wow, but now nothing helps, and no matter how hard I try, I always have overlights, I turn on one of the above programs, 1600 nits are activated and everywhere on the white there are overlights, please tell me how to do so that there were no overlights, mpv configuration made different tonemappings for iina I have MacBook Pro m3 max what I can do? 26.0.1 (25A362) OS
