Human eye dynamic range is 20 stops or 1,000,00:1.

Good LED panels can have a dynamic range of 10 stops or 1000-2000:1
This is similar for EVFs apparently.

Ability to print is even worse than LED screens with a dynamic range of 6 stops or 64-128:1

So looking at prints tends to be more pleasurable but less discerning!  This is not what people tend to consider to be the case when they are doing assessments.  


HDR is a technique so it is a human driven process that is dependent on the human eye, monitor and aesthetic abilities.
Post processing in general follows this as well but HDR are seems to bring out the horrors of excesses!

Regarding MP in cameras.
I have purchased and love the Z7, D850, D800, D500, D600, D3S, D3, D700, D300, D2X, D1X, D1.  I also had a D200, D100, D90 and D80, D70. The D200 was a fairly good camera but not up to snuff when compared with D3 and D700.  The D100 was not a great camera (IMHO). The D90 was/is a pretty good as I still have it, and similarly the D80.  The D70 is a good little camera but the horribly small TFT screen on the back (not bad for its time) is a limitation.

My perfect camera would be a 30MP D3S with a lighter option of a D800.
The D850 as you say has too many MPs for general use but it is a brilliant camera with much better features than any of the other cameras I own or have owned.
If you want to be able to shoot and crop then it is perfect.  If you work carefully and slowly then in truth a 25-30MP will give you more than enough.

I find the D500 to be a stupendous camera for fast action and birds in flight but if you start to crop then the image seems to go noisy very quickly!
I use my D600 for general stuff but in truth I choose the Fujis cameras with better/similar IQ and similar 24MP.  The latest XT3 and now XT4 are now on a par with Nikon D800 for AF performance.  I actually prefer the control layout of the XT3 to any other camera I have had except the Nikon F3.

The Z series is brilliant and the Z7 has all the features of the D850 and more.  There is a 'but' though, for me the mount jump (from F mount to S mount) is a complete distraction and has been driven (IMHO) by lens designers looking for a job, rather than consumer need or desire.  I understand the design opportunities and flange distance in the Z series is less than the DSLRs but a metal ring is cheaper than all the changes to move to a S mount set of lenses.
BTW:  I understand the idea that manufacturers need to increase profits and consumerism to feed the greedy shareholders.  I dont espouse these beliefs!
