if you are an amateur musician I am sure the kemper can sound to your ears exactly like the real thing,
just like when you play a MK solo with your guitar and you think it's 100% perfect while there are 100000 errors
even Guy Fletcher and Marcus Cliffe (the guy who originally showed the kemper to MK) wrote several times
it does NOT sound like the real thing
Again: what is the "real thing"? The sound of MK has changed significantly over the years and his Tone King with a Strat sounds completely different than e.g. his Pensa Suhr with an overdriven Soldano amp.
When I listen to some recordings I think that his sound is much too grainy and scratchy nowadays - because of the pickups / amp combination. I'd prefer a good modeling to these sounds anytime.
The reason why I have been avoiding modelling for many years was not only the sound (which is getting more and more perfect) - but the feeling while playing. You always had a latency and a feeling you were not realy connected - if that makes any sense.
Even this has been improved so much, that modelling / profiling is now at a point where even professional musicians use these amps - not just amateurs. It is all over the world on literally thousands of records by renowned musicians.
The great Jerry Donahue even used a Morley JD10 Jerry Donahue Amp Emulator extensively - which is a very basic tool. And he always sounded really good.
Is the "real thing" also a cheap chinese tube amp for $200 - just because it has valves?
Does that compare to a Two Rock for $3000 or a Dumble for $50.000? Certainly not.
It is no rocket science to emulate a one channel amp with such a basic layout like the early amps have and MK uses.
The magic comes from his fingers.
