Found elsewhere - a frame-by-frame pic of the hyperspace ram scene:
One thing that stands out - the Supremacy is close enough that, if the Raddus was still in realspace when it hit the Supremacy - it would still be visible - it didn't have all that far to go.
But instead (frames 6 and 7) it disappears - then we see the Supremacy get torn in half.
This, to me, supports the notion that first it enters the other dimension that is hyperspace (hence the "vanish away" effect of the Raddus appearing to disappear into infinity) - and then, while in hyperspace, the Raddus collides with the Supremacy and we get the effects we see.
