It seems that using an environment setting is required. Attempts to
use -co and --config “GDAL_TIFF_INTERNAL_MASK=NO” resulted in a
warning or error respectively:
--config GDAL_TIFF_INTERNAL_MASK NO
/Warning 6: driver GTiff does not support creation option
GDAL_TIFF_INTERNAL_MASK/
//
/FAILURE: No target dataset specified./

> I find that if I do:
tiffcp sample-no-mask.tif,0 x0.tif
I get an "x0.tif" with just the jpeg image, and not the mask.
That may be helpful for you (without uncompressing the jpeg image).
tiffcp doesn't use the raw interface of libtiff, hence JPEG
decompression&recompression will occur.
tiffsplit avoids that as it does use the raw interface:
tiffsplit sample-no-mask.tif out
will generate a outaaa.tif file with the original JPEG content (the
geotif tags will be lost however, and will have to be reinjected
