Uhhh... it depends... heavily.
For example Oxygene 2 and Equinoxe 4 use the Eminent Strings as they are, with very slight eq, to smooth things out for the first track, and to kill the fundamental a little in the second one.
There's a lot reverb and some delay on the first, and some reverb and a lot of delay on the second.
And if you compare those strings to the Eminent 310's output, it's very close to how the organ sounds. Both tracks showcase the strings in the higher octaves.
At the beginning Oxygene 3 has another demonstration of the strings in their higher octaves.
Equinoxe 1 is another example of clean string use, across the whole octave range, but the mix obscures them somewhat.
Most of the other tracks either put the strings in the background, or pass them through the Small Stone -> EQ -> Delay, which changes them significantly.
There are clean sources of the Eminent online, to check the sound out for yourself.
