No Philodendron Micans and Melanochrysums are not the same plant. When Melanochrysums are juveniles they look similar and often get mistaken for the other at this stage. Micans are a vining Philodendron while Melanochrysums are a climbing Philodendron. Micans are common to see in plant nurseries and even big box stores. You can see the difference between the two in the image below.
