You do realize that the brand named profiles are actually profiles created by Adobe, not the various camera makers. Adobe has tried to build those 'brand' profiles to closely replicate what the camera maker applies using the camera maker's proprietary software and/or processing applied to in-camera jpegs. Try as they might, they will never exactly be identical to the camera maker's look.
In essence ... all the veracious profiles included with ACR and/or Lightroom are Adobe profiles.
Does it matter?
If the profiles available you can choose any one or multiple, dependent on image type, and use that as a starting point.
Having a consistent starting point, that you are used to, is more important than the exact match to any in-camera profile.
