Support for intel core ultra 7 155h

In the 17.1 release, it mentions support for "Intel Core Ultra processors," but what does this really mean? I have the Intel Core Ultra 155H and the 6.5 kernel, for example, in Ubuntu the integrated Arc graphics are not supported, and you have to forcibly upgrade to at least 6.8 to be able to access screen brightness regulation. Does Zorin OS have compatibility with Intel Arc? According to what I've been reading, only version 6.8 supports Intel Core Ultra, and version 6.9 is the one that actually improves the performance of this processor. So I'm left wondering what it means when the release notes mention support for Intel Core Ultra. Is there anyone here who can comment on how well the integration with this processor has worked for them?
