Babies who are on neocate LCP formula, do their stools looks like this?

My baby has been on neocate for cows milk allergy since end of Jan and I’ve noticed stools that look like this (with the dark bits in) from around a few days after that, pretty consistently to date. She’s combination fed but I have a milk-free diet and have done for months. Dietician wasn’t sure about it but my GP doesn’t seem concerned. I haven’t seen anything similar from babies on this formula so far?? I think it’s a realllllly dark green but appears almost black
