Very light colored & Albino fish are prone to skin pigment blotches. The dark blotches could also be a reaction to water parameter problems.
If your water chemistry is stable and your BP is eating and otherwise acting normally, likely no worries.

These fish need plenty of space to move around, and they can be quite shy before they get to know each other. As such, you should be able to provide your parrot cichlids plenty of hiding spaces. Litter your tank with logs, caves, and decorative dens while also ensuring that the tank doesn’t become too cluttered.
A tank that is tall while also being wide may suit your parrot cichlids more effectively than a tank that is merely wide; the room to maneuver will lessen the stress that your cichlids experience."
"These fish enjoy their privacy and are a relatively peaceful bunch. They’re especially playful once they get to know the other fish in the aquarium, and can be generally pleasant fish to have in a group tank."
"Do take care, though: while it’s unlikely for blood parrot cichlids to revert to the aggressive nature of their genetic ancestors, over-stressed cichlids may become defensive and attack other fish they interpret as the source of their irritation."
"Blood Parrots, especially when young, can be very shy and reclusive. Its typical for them to hide when you first bring them home to hide and/or be very skittish and can take a few weeks for them to adjust to their new surroundings. Some ways for you to help them adjust is to make sure they have several hiding spots and adding some dither fish."
"Stress Spots: This is usually mistaken for Neascus (Black spot disease). Blood Parrots sometimes get Stress Spots which are black splotches on the body or fins and this is caused by stress. This is typically present you bring them home but can also show up when in cases of shyness, bullying, breeding, illness, or sometimes nothing at all. The splotches will usually disappear after awhile once the problem is taken care of."
