Correct .. even the flat rubber sheet model is deficient.
There is no geometrical centre in the BBT/expansion model because this still implies that something is not expanding which doesn't align with observations nor the Cosmo Principle.
The rubber sheet model helps to visualise the observable fact that no matter where you are located on the sheet, everything looks as though it is expanding away from everything else as it stretches. This more closely aligns with redshift observations.
