I like what Line6 is doing with the Helix where there's a little icon of the amp or pedal - or a bigger one with the otherwise not that useful grid view in HX Edit / Helix Native. It gives a little guide towards what the amp or pedal is based on, but then doesn't impart any skeumorphism to how operating the model works.
If they want to give this sort of cues, to me they should end at the "knobs look a bit different and there's a different background color" level, rather than painstakingly realistic renditions of tolex and grillcloth.
I think Mercuriall has the right idea - you get that "this is a Marshall" vibe, but without wasting a lot of space on fluff.
Speaking of right ideas. Noise gate, overdrive, cab sim adjustment, a few advanced controls and the main amp controls all in one view is a pretty lovely way to combine it all.
