Running the AF tweaked Harman curve . I do find it bright on some recordings , but put that down to the Focal K2s tweeters. But then again, I like the detail.
Had some ribbon tweeters a few years back in the wife’s car. They where next level bright. Great detail , but on closely micd female voices I’d just cringe.

My take on this is drivers have a larger influence on brightness than target curve.
