The "CPU" (that is, the generic compute part) cannot encode 4K video in real time, that part is handle by codec-specific HW.

They aren't doing JXL encoding in hardware though. Zero chance that the new iPhone chip has hardware acceleration for JXL. Definitely just plain old CPU encoding.

And we're not talking about video anyway, this is about ProRAW, a still image format.

Given apple design their own camera controllers and have their own chip design teams, I wouldn't be nearly so quick to conclude that.
