I find this one a winner for colored foliage where it is very stable. It does not revert back to any mix parentage and the foliage are somehow appear to be uniform. This one is reverse of Dieffenbachia amoena (or the common ones)
This one has 2 tones colors the edges and midrib are dark green with cream full surface. Multiple branches are sprouting out from a singular stem - having a characteristics of a compacta or maculata.
Perhaps they are hybrids from this parentage.
