Building the codec string
Four fields, dot-separated, and a support check that returns false for every kind of mistake without saying which one you made. Assemble a string here and it is probed as you change it — including against a deliberately wrong field, so you can see that the answer is the same either way.
Assemble one
Probing…
The casing option is not a trick. Codec identifiers are matched exactly, and Opus inside an IAMF string is not the same token as opus on its own — a string that differs only in case is a different string, and returns the same unhelpful false as one with an invented profile.
What each field carries
| field | current | what it selects |

Near misses, probed together
The string you built, next to variants that differ by one field. All of them are asked at once, so an unsupported answer can be read against its neighbours rather than on its own.
