When I use CRU just editing already existed refresh profiles I no more have Brightness Control for some reason.

Someone else reported this with a different laptop, and we determined that any EDID override causes this to happen, so there's nothing I can do about this. It seems to be an AMD-specific driver issue. Try adding a custom resolution through Radeon Settings instead.

If this only happens on pages with video, then it sounds like the memory clock issue described in the first post. Did you try the "LCD standard" timing option (or "CVT-Reduced Blanking" with Radeon Settings)?

It's not that simple. Some games won't use the higher refresh rate when using the NVIDIA control panel unless you also create and install a monitor driver, and it doesn't automatically choose the best settings. It just uses whatever happens to be set for the native resolution.

Adding a custom resolution with AMD should be easy, but you're assuming the same refresh rate and timing parameters will work with different hardware. It might not even have the same panel interface inside despite being the same model, so there might be different limitations.

This is what another guy with same laptop and nvidia GPU sent me

But when he sent a picture with written 100Hz those greyed out numbers didn't change except Hz number. And monitor isn't much more stable with those on 96Hz (slight stroboscoping on dark colors).

That looks like the CVT-RB timing parameters for 60 Hz. That's what the NVIDIA control panel does. It just uses whatever happens to be set for the native resolution. If the same timing parameters don't work with your laptop, then the hardware is different.
