Comment (by pdr0):

 extractplanes=y is probably more "elegant" than scale with format
 conversion . The 10bit Y plane is equivalent to the gray10 (just
 discarding CbCr planes)

 {{{
 ffmpeg -i test3.mp4 -i test.mkv -lavfi
 "[0:v]extractplanes=y,settb=1/AVTB,setpts=PTS-
 STARTPTS[main];[1:v]settb=1/AVTB,setpts=PTS-STARTPTS[ref];[main][ref]psnr"
 -f null -
 }}}
 PSNR y:inf average:inf min:inf max:inf

 {{{
 ffplay -vf extractplanes=y -i test3.mp4
 }}}
