Your observation that this may be a wootz blade is very interesting, but I think it is unlikely. I would like to see clearer pictures of the pattern, which in places appears (to my eyes) to show lamination. There are (almost) no examples of wootz being used among the Muslim groups of the southern Philippines, and those one or two that have been reported may not have been true wootz. There is no clear evidence that wootz was actually made in the Philippines, or the wider Malay world as far as I know.
Is it possible that you are looking at another form of crucible steel with dendritic features, such as a piece of Spanish steel that has been repurposed? The technical details of wootz are outside my field, so I shall defer to those with more expertise.
I will say, however, that the historical evidence of Philippine edged weapons made from wootz is scant to non-existent. Laminated blades are the norm, with later monosteel.
