Just to be sure we are talking about the same thing, what do you call "fail" 
exactly ? Is it that gdalinfo doesn't report "NoData Value=-999" for the bands 
?

Just for reference, I've create a fake 
"LSatThermalCube_96-98_float_cmsk_landmasked_ll.img" and  gdalinfo on it 
reports :

Driver: ENVI/ENVI .hdr Labelled
