Each substance has a different effect on DMT visuals so there is no 'law' that says visuals increase or decrease with MAOI dosage.
A substance may also alter DMT visuals, rather than increasing or decreasing them.
With Caapi, most of the time, a higher dosage in the first place prolongs your experience. Another effect is that the higher the dosage becomes, the more difficult your coördination will become and the heavier your body will feel. I personally find that visuals are not so much increased or decreased by caapi, but energized.
But each type of caapi (yellow, white or red) is different as well.
Rue also alters the visuals of DMT, but in a different way than caapi does.
Caapi is by far superiour to rue.
Other types of MAOI used, will probably leave their own unique mark on the effects of DMT as well.
