I have a Focal Elex with fenestrated sheepskins pads, so I think I should reply even if I haven't had the pleasure to listen to Utopia yet. With these pads and if I use something like MorphIt to EQ them with Utopia as a target, I would get very close to the real deal, but they will never match the speed of the beryllium drivers. So, yes technicalities are definitely a think when frequency response is determined by the physical properties of an unusual driver material.

I don't have the time or knowledge to answer for all types of headphones technicalities, but I can speak of slam or punch.

I believe slam is unrelated to the frequency response. It has to do with the volume of air the driver can move at once. If the whole audio chain from file format to DAC, amp then headphones is optimized to maximize dynamics, slam is definitely perceptible.

See this thread

or this post for more details.

By fenestrated sheepskins pads you meant original Utopia pads? Or it's from decony? Without eq, do you liked sound with these pads more than with Elex original pads? Or differences are subtle? Resolve says that Utopia pads significantly improved FR in Elear, but they cost half the price of my Elex, doesn't seem like a good deal

They're from Dekoni audio. I would say that they improve details perception in the treble without any detriment to the bass or mid range. I should have the opportunity to listen to Utopia 2022 in a few weeks and I'm going to try to compare them to my Elex
