Is the purple Instagram DM update a hint that Meta is fully integrating Insta

Heard about this for quite a while and I feel like they're slowly merging both their apps into one. According to one of the growth strategists I follow, who works with boostbysocial, this purple instagram dm color change is one of the first visual cues that indicate that the whole of Instagram has been integrated into the Messenger. Do you really want this? Or is it imposed on users? So how will Instagram-only DMs be handled?
