i suppose it comes down to how many bands you need to tweak but the ability to move the bands is basically what the studio EQ (parametric EQ) does with the added ability to set the Q width which a graphic doesn’t have.
The issue is you really only have two bands you can do that with in the studio eq. The low is again set at 150 and the highs are set at 8 or 10k, I can't remember off the top of my head.
My issue is more where all the hard frequencies are set in all the Kemper eqs. For instance, if a rig is a little boxy I would take out a little 500hz if it is honky then 700-1k is usually a good start, so a 1k band can do that, where the 1.2k in the graphic is a little too high for fixing that. Usually bite is at 2-3k and low mid flub is usually around 250.
Having a couple more bands is always nice to have for whatever you might need, as well.
I am not saying to make the graphic EQ more like a parametric, just saying the set frequencies of the graphic could have a few different presets where you can pick the list of set frequencies, depending on your need.
