One can treat the uniform component scores the same way you treat the partial warp scores for the non-uniform part of the W matrix. You can, for example, compute distances among all pairs of specimens using the uniform component and compare this dissimilarity matrix to a similar one computed using just the non-uniform component.
Note: the decomposition is, perhaps, elegant mathematics but is not based on any biological model so I think the distinction is a bit artificial - unless you have a situation where you believe the distinction makes some biological sense. -------------------- F.
