The capability ALLOW_COLOR_INDEX_WRITE cannot be set in the constructor. See the documentation for IndexedGeometryArray for what format values can be set in the constructor.
The format values are ORed together in the constructor and if you look at the values of the format constants, you will set that ALLOW_COLOR_INDEX_WRITE and COLOR_4 both equal 12. So, the bit-value for COLOR_4 is set when using ALLOW_COLOR_INDEX_WRITE in the constructor.
