The LED collar issue actually KEPT me from buying the rack. The LED collars on Bass - Mid - Treble - Presence are huge and not just because they look cool - They give you an indication where these knobs are in their range even when they haven't been touched in the last few seconds. With a profiling amp the numeric values of those knobs comes up on the screen when you rotate a knob - but goes away after 2 seconds.
This is an easy fix for Kemper with a software update - they need to put the values on the LCD screen right above each knob and let the values stay. As it stands you need to actually jiggle the knob to get that numeric value to pop up on the display. That's a pain when there are 4 knobs that are often adjusted to dial in a sound in a home studio situation (I have racks for my gear at home).
The screen should always have the numeric value like this:
Bass -1.5 Middle +2.5 Treble -3.0 Presence +4.8
