In this case Preflight validation fails with this message:

2.3.2 : Unexpected key in Graphic object definition, The ColorSpace is unknown

PDF Reference v1.4 Chapter 4.8.6 table 4.40 indicates the abbreviations for the names of color spaces, which could be used to represent color spaces for inlined images instead of using the full names. There abbreviation *CMYK* matches full name *DeviceCMYK*.

The culprit is that {{ContentStreamEngine}} looks for the corresponding {{ColorSpaces}} enum constant by matching its name to the specified color space name in content stream (i.e. using {{Enum.valueOf()}}).  While {{ColorSpaces}} enum class has constants for abbreviated names, they are stored in local variable {{label}} and do not correspond to the enum constant name.
