Quality Of Pin

Is Pinterest able to guage the quality of the graphics of the pin? I am guessing it can because, I do not see any poor graphical quality pins. I ask because while my graphics are good, I am not sure it can match the very best on this platform.

I don't think so, and I tell you this because of my tests: a\b on different accounts the same image with lower quality and different sizes. They seem to perform both very well. What matters the most is engagement. Said this, in theory, good quality images are always better both for people and algorithms.

I don't think so too.
