I don't get to experiment much with the Kemper in live venues and rely mainly on headphones. Not ideal but the only way for me at the moment.
But I recently read this in the manual and wondered why 50% stereo/90% stereo settings would be recomended to give the nicest stereo image. I pretty much use just delay and reverb in stereo.
Thanks
It’s not 90% but 90 degrees of phase shift.
And 200% on Stereo parameter of the effect gives you the widest spread.

True.
To relate this to the OP's question, I believe the reason that Kemper don't recommend this at the "nicest stereo image" is that it can leave a hole in the middle, id doesn't sum to mono as well due phase issues etc.
the 90° (50%) phase variation between left and right is what is most commonly used in stereo rack or pedal effects
