FWIW - My wife used Goof-Off to remove old latex paint splatter from
stained wood ceiling beams in our living room and kitchen.

Worked great - it removed the splatter and did not appear to remove the stain.

She tried not to let the Goof-Off soak into the wood - she just wiped
at the splattered areas until the "bad" paint was removed. Only took a
minute or so in each area.
