Could be that the LA-2A is harder to model than the 1176 but my main point was that how do you know what they've modelled and what not? Are you working for UA (my guess is not..
Read it like this, they call it modelling, which it most likely is but the models them selves and the individual components in the models are probably simplified versions of the real deal which leads to the slight difference in sound/compression character.
About that "unit to unit variation" I agree with you, that's marketing hype, nothing more but the compression action itself on the 1176 emulatio is impressive and does give the feeling that it was truly component modelled.
