It is simple, considering number of bands, DataType and
ColorInterpretation we decide LayerType,  for LayerType we set
DrawingStyle and each DrawingStyle has assigned default renderer.
Shortly:

multi band => MultiBandColor

single band and color interpratation PaletteIndex => PalettedColor

single band and color interpratation ContinuousPalette => ContinuousPalette

single band and data type ARGB32 => SingleBandColorDataStyle

all others => SingleBandGray
