This is true, I got the free version initially and thought it was good but not great. When I got the full version though, wow. The various knobs and buttons actually do things, specially the oversampling.. when you get to 8x oversampling in precise mode you get into real e530 territory and I haven't even EQ'd or done anything else with the tone.The very claim "realistic amp" tone within digital realm is bullshit to me. I like U530, but there is no actual demo version of it.
