Only a CoronaCeck test result certificate is valid for 24 hours. Certificates of vaccination and recovery are valid for much longer (https://coronacheck.nl/en/faq/1-4-hoe-lang-is-mijn-coronabew...).

Are there places which are legally required to only accept test result certificates?

Not in NL. Why does this matter?

For me, elective medical procedures and air travel required a recent (<24h) test result, vaccination was not sufficient.
