Because the profile would already be embedded in the DNG file. (and the jpeg copy already has the lens correction profile applied to it)
(
It may say "built in" but does not correct for perspective or horizon distortion. In fact, there is no specific profile for the Air 2s. It is easily tested by simily choosing Osmo, Inspire or Mavic Pro profiles (presets). You can see all the changes.
The problem that is not solved is horizon distortion when constructing a pano from "wide angle" DNGs. No problem with 180 degree DNGs. It's all because the images are tilted (rotated) in the wide angle DNG set.
No one has solved this problem of horizon distortion.

From what I can tell the embedded profile in the Air 2S only does vignette correction.
Note that lens profiles don't do "perspective correction", but they can do distortion correction (and with a "flat" image you can then apply perspective/etc modifications in software).
@robgreaves you say you like the images from your Mini 2?
I decided I wasn't quite happy with the images from my Mini 2. Both the vignetting and the stretching towards the edges.
So I set up my import scripts to use Exiftool to remove the embedded lens profiles (exposing the underlying image in Lightroom/etc). And then created a fresh lens profile from scratch, and made it default for the Mini 2. Along with a custom dual-illuminant DNG colour profile.
Now I really like the Mini 2 images!
If I had an Air 2S I'd be making a fresh set of profiles fairly early on. It is a bit of investment in time, but I think it pays off. I don't know how much inter-sample variation there is across the Air 2S population, but a custom profile would obviously be made from that specific camera.
Adobe provide the tools for us to build our own profiles, but it does need some careful work to make a good one.
I've done it for many of my SLR lenses (including when combined with teleconverters) as Adobe doesn't provide all possibilities.
A good lens profile will cater for variation in focal length, focus distance, and aperture. Essentially we make "sub-profiles" for a variety of settings, and Camera Raw will then interpolate between them for the current photo's settings.
The Mini 2 is a nice simple case, with one focal length, fixed focus, and fixed aperture.
The Air 2S is only a bit more complex. Probably one for hyperfocal/infinity distance, and one for something closer.

The baked in lens profile isn't that great.
I would suggest downloading the trial version of DXO PureRAW and give it try. It corrects distortion, vignetting, along with almost unbelievable sharpness optimization and noise reduction. I've been using it for the past 6-8 months and at this point it's part of my normal image workflow for both my drone and DLSR photos.

If you're interested, have a look at PHOTONINJA, not freeware, but worth every penny and the only piece of RAW editing software I've happily paid for. Been using it for the last 5 years. It features a non-AI 'learning' distortion correction module based on the HUGIN lens correction GUI that does a remarkable job.

I haven't heard of Photo Ninja, but it sounds like an interesting approach. It looks like both programs are about the same price $120. I only mentioned the trial because I'd feel bad if someone paid for a license and didn't like the program.
Thanks for the tip on Photo Ninja!
