Was expecting OOK but received this

Hey everyone, I am trying to decode this signal, but I am not sure what this actually is. I was expecting an OOK signal based on similar products.

This is a chinese wireless transmitter that broadcasts a signal at 433MHz to wireless receivers...basically remote relays. The main transmitter I want to replace with an arduino for more intelligence.

Unless your data has been captured poorly, that looks like pulse-position modulation to me.
