.....Most newer sensors using 14-bit raw, even crop sensor cameras, can produce superior images without having to resort to ETTR/EBTR.
Superior to the images produced by the older cameras, but with ETTR they produce even better files (i.e. data rich, noise-free and resistant to much pushing and pulling in PP). The advantages of ETTR are less than they used to be, but they are still advantages (for the time being).

They continue to be difficult or impossible to demonstrate in real life scenarios.
In particular, daylight exposure for landscape based on Sunny 16 at or near base ISO is noise free with any camera made in the last ten years or so. It doesn't call for ETTR or EBTR.
It's the darker scenarios - sunsets, night images, action, etc. - where ETTR begins to be useful.

Maybe the image that started this post is an example?

You can extend that to include anything which needs brightening - which often applies to the darker areas (shadows) in a typical "normal" exposure. That's one of the things I'm referring to when I say "pushing and pulling". You keep saying "difficult to demonstrate", and that refers to the more recent cameras, but for the time being there are still advantages to be gained, especially if you don't have a recent model (mine's a D5200).

Don's sell your D5200 short. As a 24 MP crop sensor it's only one stop short of the performance of the D610.
In other words, if I can't see noise in a daylight landscape at ISO 200, you should not see it either at ISO 100.
To put it another way, I usually use f/11 to avoid the onset of diffraction. With your crop sensor you should probably use f/8. At ISO 100 I might use 1/200 sec and you could use 1/400 for the same daylight scene and probably neither of us would see any noise.
Of course, if you go looking for noise (boosting the shadows a lot, viewing at 400%, cropping a lot, making large prints) you are going to find it.
I try to not do anything obscene with the processing of my shadow information.

Hi, Tommy,
The camera manufacturers do not determine the ERADR for each individual camera, because it is extremely variable among cameras of the same brand and model. Hence the need for the photographer, if he plans to capture the best possible quality of image data, to test his own camera for its ERADR and to determine its loss of ERADR with increasing ISOs. With different individual cameras having the same ERADR at base ISO, as ISO is increased each camera will gradually lose ERADR at unpredictable rates. Again, each camera must be tested.
How to test your camera’s ERADR is covered in first of the two links I posted earlier.
