Or, the Realiser can simulate 7.1 (for example) from a measurement with any number of speakers, including just one.
No.Realiser will simulate the speakers that were not available to measure.
You can measure with one speaker in different positions (or with yourself in different orientations towards the one speaker in a fixed position), but the Realiser will not simulate that speaker in a completely different location where you never measured it. (Except when interpolating between the 5 points for countering head movements, that is a limited range about 30° max between the points. Extrapolation beyond the outer points is not possible.)
[Edit: I think my words could be misinterpreted, so to clarify more: you can measure a complete many-speakers system using one speaker in different positions (or with yourself in different orientations towards the one speaker in a fixed position). But if you only have one (3 or 5 point) measurement (for example only for looking straigt at it, and 30° left, and 30° right, and 30° up and 30° down for the interpolation purposes) of that speaker, the Realiser can not simulate that speaker in positions to your side, or behind you, or above you. (In theory it could use the looking 30° left measurement to create the front right speaker, and similar for the left front, but then you could not have head-tracking anymore.)]
