If I compare it to my Namwah and Blue Java bunches it probably looks more like my Namwah bunches. The blue color of my Ice Cream bunches varies with light and ripeness of the fruit but all have that silverish coating what I do not see in your photo.
The other clue that makes me think it might be a Pisang Awak/ Namwah type is the purple coloring on the band of the banana pedicel. But this trait also varies with maturity here: it will be there the first few weeks but it is definitely gone by harvest time.
You will definitely know by the time they get ripe: Namwah bananas will be yellow ( maybe not that bright than a store bought Cavendish) while the Blue Java just turns to a pale yellow and never looses the silverish coating.
Here are some photos. Photos were taken and uploaded with my phone this morning, I do not have any photoshop skills. Sorry for the bad light, but I hope you can see the differences at the various stages.
