Is Assertion verification same for all formats?

[RDevR99]

In verifyAuthenticatorAssertionResponse(), there is this condition : if(authr.fmt === 'fido-u2f') and then all the logic for verification.

However, shouldn't the logic for verifying assertions be the same for all formats?
I have commented this line out and it gives me a positive verification for android-safetynet.

So, should this if condition be there? or are things actually different for different formats?

How did you verify the android-safetynet attestation?

Does anyone know how one can verify the android-safetynet attestation?
