Stephane,

Currently there is no way of querying a TIFF file from the GDAL
API to find out the interleaving mode.  Is there some reason you
need to do this?

Generally speaking I do not try to expose image organization
information through GDAL's metadata facilities as the application
shouldn't need to be aware of it.

Best regards,
