I was not referring to anything you might have done, just remember the 
Camera in the iOS devices is an App.
All jpeg files in any camera have the raw data from the sensor 
processed with various proprietary processes to produce the jpeg, 
regardless of you letting any apps touch the iOS images, they have had 
the sharpening, saturation, WB, contrast, the iOS developers determined 
was required for the production of jpegs within the iOS cameras. The 
production of HDR within iOS is not true multi-exposure HDR, unless you 
have an app which does that.
...and you don't get iOS RAW files from the iPhone, ...yet.

True. However it will still be an apples & oranges comparison as the 
NEF viewed in Preview will not have the in camera jpeg tweaks to 
sharpening, contrast, noise reduction, etc. made in the iOS devices. 
The D70 NEFs were notoriously "soft" and low saturated and always 
required some fixing in ACR.
BTW: You have a dust spot up there in the sky. That was another big D70 
problem, it was a major dust magnet and I learned all my sensor 
cleaning skills because of it.

I am certainly no professional photographer, but I have 50+ years of 
experience under my belt as a film/digital shooting 
hobbyist/enthusiast. That includes 14 years of experience with digital 
photography.

I believe I said that I looked at 100% crops of several different areas 
of each image, when making that comparison the foliage in the iPad 
image is obviously out of focus, it is not in the other three. That is 
not a criticism of the iPad's photographic ability, but of the image 
presented for comparison.
The iPhone shots are OK, with the difference between the two being the 
blue sky being visible in the HDR treatment. Since there is little 
difference between the the quality of each and the HDR is produced from 
the basic camera , I hold that the non-HDR is the better of the two. 
There is also a dynamic element absent from all three of the iOS images 
resulting in a slightly dull appearance to them when compared to the 
D70 shot.

Then just looking at the overall effect of each and the wider DR is 
quite apparent in the D70 image when compared to the other three.

Therefore I stick to my original conclusion regarding the devices used 
to produce the four images you provided. Ranking them D70, iPhone 
non-HDR, iPhone HDR, and bringing up the rear the iPad.

Again with a different four images, with different subjects, and 
different lighting I might come to a different conclusion.
