FLAC and Wavpack (likely others too) use error detection codes for uncompressed audio data.
Why not for compressed?

I could find only 2 differences:
-you have to decompress the data to verify correctness, which (sometimes greatly) reduces verification performance
-you have more data to be checksumed, which slightly reduces compression / verification performance

What am I missing?

FLAC does store the checksum of the whole audio data.

Where did you get the idea it doesn't?
