I've tested this in Caldera, but if you customize the droplets within an existing profile, it will not be accurate. If you only use 7pl droplet, the image will print extremely light.
You would need to make your own custom profile and max out the ink limit, to compensate for such small ink droplet and even then it may be too light and lacking contrast. Where limiting large droplets works well, is on porous materials, such as wood, but within limits.
One area where I use custom droplets is for white ink. I'd tested printing white swatch with 100% droplet #6 on express mode and nothing restores white printhead nozzles better. I could purge and status check many times or print a white swatch with largest droplets and the latter is more reliable to get all the nozzles firing.
