 No, this information is not available. Note that it is more 12 MBytes
 than 15 Mbytes anyway.

 The current implementation of OGL dL is a 32 bits word for a token
 (instruction) and a word for each parameter, which you can use
 to estimate the size of the DL. This of course may change without
 any notice, as this is part of the OpenGL implementation

 Look at glListParametersSGIX extension. The priority mechanism is
 the only way to have some control out of that cache memory.
