ohmygod! It works! At last, after working on this for 4 months; judder-free movies on 60Hz TVs.

For BD movies:
ffmpeg -i IN.M2TS -vf "telecine=pattern=5555,bwdif=mode=send_frame" -avoid_negative_ts 1 -c:v 
libx265 -crf 20 -preset medium -c:a copy -c:s copy OUT.MKV
For soft-telecined DVD movies:
ffmpeg -r:v 24000/1001 -i IN.VOB -vf "telecine=pattern=5555,bwdif=mode=send_frame" 
-avoid_negative_ts 1 -c:v libx265 -crf 20 -preset medium -c:a copy -c:s copy OUT.MKV

For some reason, in the DVD movie, I'm getting only Japanese dialog, but the video is stunning *and 
judder-free*.

I will work on this more and provide a good documentation write-up.

(I think this is a game changer regarding telecine.)
