This is an EQ profile for v4a's EQ bands from a moto g6 plus running Android Pie and Dolby audio in Music mode. Taken with a Dayton EMM6 with Room EQ Wizard. I have Impulse Responses (for convolution) for the same target curves but can't link to them because of XDA rules.
House curve target (1.8dB/octave rise from 100Hz to 20Hz, 1.8dB/octave fall from 1 kHz to 20 kHz):
The house curve sounds warmer than the flat curve.
