You do understand that 100% monitor view does not represent any real world viewing condition. To take about sharpness in any absolute terms in regard to pixel pitch does not mean much.
I wonder myself just how many contributors on this forum actually realise the full significance of a 100% view of a small crop of an image on their monitor, in terms of equivalent print size.
The result will vary according to the size and resolution of one's monitor. If we take what might nowadays be a fairly typical monitor size of 24" diagonal with a 16:9 aspect ratio, and resolution set at an HD 1920x1080 pixels, then the resolution per inch of screen, both vertically and horizontally, will be about 92ppi.
With this information at hand, one can easily resize any image from any camera in Photoshop, using a resolution of 92ppi, whilst maintaining the same original or native file size, and see what dimensions result.
The 103.4mp image from a D800 (in 8bit mode) would produce a 6ft 8" x 4ft 5" print at 92ppi with neither interpolation nor discarding of image information. (For the benefit of those not familiar with the old-fashioned American system, that's 2032mm x 1346mm).
If the resolution of one's monitor is set to a lower resolution than 1920x1080 pixels, then that equivalent total print size containing the 100% view of a crop, will be proportionally larger.
When doing real-world tests to determine the significance of such minor differences in resolution, according to F/stop used or quality of lens used in relation to a given camera, I'm first interested if there is any noticeable difference at all, at 100% or even 200% on the monitor. If there isn't, then the matter is quickly settled.
If there is a slight but noticeable difference in detail, clarity and resolution in any comparison I make, at 100% or 200% view, then I make a note of that fact and interpret the significance of such differences in terms of output size, or print size.
Such difference may be of no significance whatsoever at the maximum print size from my printer, which is the 600mm wide Epson 7600, if I print the full uncropped image. But what happens if I significantly crop the image before printing?
It's not inconceivable that I might want to make a moderate size print of the 100%, or 200% crop that I see on my HD monitor. I expect my print to match the resolution and detail I see on my monitor.
If I see differences in detail between a D700 shot at F16 and a D800E shot at F16 at 100% on my monitor, the D800E shot being slightly, but noticeably, more detailed, then I understand that such differences would be irrelevant if I were to print the whole scene at A3+ size (or even larger), but such differences would not necessarily be irrelevant if I were to print just the 100% crop I see on my monitor at A3+ size, or A2 size.
