Comment (by Balling):

 libavcodec is better now 784234 Bytes... But !!! It does not store the
 alpha channel and if you will save tiff in photoshop 21.1 without alpha
 channel it will be... wait for it... 605392 Bytes! Just wow. With alpha
 channel it will be the same (algorithm in Photoshop is the same, bite
 stream is the same, though some metadata is different). Maybe will try to
 check libtiff.
