I have similar issue with my supposedly Ice Cream banana purchased from a local nursery. The problem is not all the mature leaves of pink midrib, only a couple of them, and my fruit definitely dose not look like Ice Cream / Blue Java...
I love this forum, it really helps to have all the banana experts help us out misidentified varieties... but I wonder if mine is Namwah or something else... I will be happy to start a new thread if need be, here are a few of my banana photos.
Planted the pup May of 2014. Flowered July 2015 and waiting for the fruit to start ripening any time now.
