SH-S203S does have LightScribe, as well as its external version.
I have found info about TS-H653E/SH-S203S chipsets (I believe that it's just non-LS and LS versions of same drive) lurking chinese websites and reading user comments via translator... But confirmation needed.
As for SH-S223M/TS-H663M, it could be an unreleased LightScribe version of SH-S223C - there were inscriptions on SH-S223C board:
Also there are inscriptions on SH-S162L/TS-H652L board:
But only SH-S162L seems to was released with this PCB...
