If the sceen is drawing 10s mA and the screen cap is 1000s pF, the voltage
will collapse quickly enough to follow the envelope of a normal two tone
signal with spacing of about 2kHz or less, so that's unlikely to be the
reason for any difference.
With two tone you won't get syllabic rate overshoot in the drive signal
because of duff ALC (if the driver is prone to that).
