Is ENOB calculation correct for example as below?

0 dBFS source sine signal has been attenuated and it's reflected in both THD+N and SNR, but ENOB stays unaffected.

Yes, it is correct. ENOB is normalised to a full scale equivalent. See the Analog Devices tutorial equation 2, for example.

Thx John, I didn't know this more complex formula.
