I don't think so. Mac sales have only grown and the whole "you need a Mac for creative work" hasn't been a thing since the 00's.
I think this is more about having the team put advanced photo editing features into the native Photos app, and possibly contributing to AI image processing.
There are lots of amateur photographers out there that use Apple hardware yet so far Apple only monetizes storage. I wouldn't be surprised to see a subscription offering that includes pro tier features for Photos.app good enough to replace Lightroom for enthusiasts but not for actual professionals.
