Fundamental Questions: ADCs, DACs, I2S

I have a question which google (despite my trying) has not been able to answer.  I hope someone here with more knowledge than I would be gracious enough as to correct my understanding on the following point:
I2S data is converted and output by a DAC relative to that specific device's own 0dBFS level and as nothing to do with the voltage the signal was originally sampled at.
example:  If an ADC (0dBFS = 2.5Vpp) samples a 1Vpp signal and outputs this signal via I2S to a DAC (0dBFS = 5Vpp), the DAC would output an analog signal at 2Vpp.
Is this correct?
