Shoot that scene on an Exmor and set the jpeg contrast too high and you'll get the same result. A 10D would cope with that.
You can screw up with all gear, that isn't a reason for or against anything. However, if you shoot this with a d750 and 13.9ev of dynamic range, my guess is that it's much easier (or possible at all) to keep the bright sand from clipping while preserving detail in the shadows - 3ev is a big, real world difference.
As for the 10d - you're correct, at iso 100 it has nearly the same dynamic range as a 5d2 or 70d (11ev) which tells us about how Canon sees the tradeoff resolution vs dr :->
Disclaimer: I totally love all my Canon gear and feel you can produce great pictures with it. Unless you shoot movement in harsh daylight and cannot bracket, that is.
That isn't a terribly challenging scene to expose. The contrast ratio of noon day sun is about 4-5 stops and the contrast ratio between the sand and darkest parts of the scene are 4-5 stops, too. So we're looking at 10 stops of contrast at most, likely less, with the exception of specular highlights kicking off bits of sand. I agree that a 10D could handle it.
I guess if you dramatically underexposed that shot it would look better on a Nikon sensor, but you'd have to be really incompetent.
Introduce a lot of backlit clouds or street lights at night or even go deep in a forest with just a few rays of light or peer into a cave or balance between the inside of a house and the outside without much light.... and you're looking at valid 14+ EV scenes no problem. Of course they would look better lit than tone mapped.
But that's why digital cinema cameras have gobs of DR (sorry, the Alexa's 14 stops eat the D800's 14s for a snack and even the C300 has more highlight detail than the 5D at least it's distributed to favor it) is because you're dealing with tricky situations without the potential to use strobes and without the time to wait on light and you're viewing on monitors/tvs/retroreflective movie screens, which have a lot more contrast than print.
But now that we see photos on our computer screens, I can see the need for a little more DR. Dealing with 10 stops of contrast on a very good screen vs 4-5 on the best prints available.
