With MegaPOV you might have been able to get something with the 
raw_image and curves post_process filters...I made them specifically for 
dynamic range compression, and the precision is better than 48 bit (the 
raw_image filter restores the full float precision colors). Don't know 
of any workaround for 3.5 though, you would have to use an external 
program.
