Then theres somthing buggy because the effect is quite vissible.
for example try:
./ffmpeg -i tests/lena.pnm -q:v 16 lowbitrate.avi

./ffplay lowbitrate.avi -vf mp=pp=de/fq:16
./ffplay lowbitrate.avi

or you can look at my few years old comparission:

Also note that pp is much faster than spp or uspp
