I dont know anyone who has a D5 but I think we need to consider that the D5 (21MP), as is the D500, while the D850 (45MP) and D800 (36MP) have many more photosites (pixels). The extra pixels in the D850 and D800 are probably detrimental to their low ability to yield low noise images as the extra photosites are competing for the same amount of light so the S/N ratio is much worse.

Also we need to remember that with each new family of EXPEED chips there are different, usually better, denoising applied to the sensor output. I cant remember where I saw it but I read a technical paper on the S/N output from various cameras and its conclusions were essentially if we want better low noise images then we need less pixels but if you want better resolution we need to get a modern high pixel count camera but need extra light (bright conditions).
This is one of the reasons I have multiple cameras - right tool for the job.

Part of my move back to Dxxx series from the Dx is my desire to reduce battery weight and to consolidate to a single battery type EN-EL15 batteries. I now only have a D3S and D700 that use the larger heavier old batteries. My aim is to release these cameras in 2019. I have Z7, D850, D500, and D800 and D600, which provide me with a huge choice of resolution and AF speed. In reality the D600 also needs to go as well as I seldom use it now I am in UK.
