If you can't tell a difference between 2 different units, no matter what they are, 2 real amps or a modeler and an amp, it means something in the chain is obscuring whatever differences MUST be between any 2 things, so there you go with this "Comparison".
That's not what it means at all. There are numerous blind tests involving the Kemper in which there is absolutely nothing 'obscuring' the signal chain, and I have no doubt you'd be just as stumped with those as you are these.
It is not valid for any statement of any real importance.
Speaking of validity, I don't have a problem with blind tests based on YouTube videos, though it seems completely ironic that you apparently don't either.
As i suggested, make a comparison of a dynamic playing from hard to soft with a tone that is not a compressed to hell distortion with all clipped waves. You will hear much much more of a difference,
The type of distortion (or "compression") you hear in the samples is common for the brand of amp that the samples are based on. Like I said, there's no external compression, nor is the distortion based on the conversion from WAV to MP3 or any type of compression algorithm. It's a product of the amp gain.
