Can LCD sharpness differ between cameras of same model?
We all know that there could be small differences in image quality between two or more same-make, same-model lenses.
Can there be differences in sharpness as perceived on the camera LCD, between two same-make, same-model cameras?

Yes, but not due to the LCD. Any sharpness differences (shown on both the LCD and your computer screen) would be due to the normal focusing variations from body to body.

In reviews and assessments of something over 500 digital SLR cameras, necessarily including sometimes as many as 20 copies of the same model, my research associates and I have never observed any substantive or measureable differences from camer to camera of the same model.
For people who have moved from a lower resolution camera such as the D200 with its 230,000 dot rear LCD, up to a D300s with its 921,000 dot rear LCD, or up to a D7100 with its 1,228,800 dot rear LCD, there will be a perceptible increase in colour depth, clarity and detail. Perhapas that's not what you're asking about though.
More directly, if you place ten D200 bodies side by side in the same room, copy the exact same photo onto ten different memory cards and place one in each camera, as long as the rear LCD menu configuration settings (e.g., brightness, etc.) are the same in each camera, then the photos will look exactly the same. Transfer the photo to ten SD cards and look at the them in identically adjusted rear LCD monitors on ten D7000 bodies or ten D7100 bodies and the photos will look exactly the same from camera to camera of the same model.
LCD monitors can drift somewhat because of component deterioration over long periods of time (in my estimation, after about five years of daily use), but the amount of drift is generally inconsqequential and varies from LCD to LCD. Note though that five years of daily use is an awful lot, although extensive use of video might accelerate the process. To see the amount of potential drift, I think it would be necessary to compare, for example, a brand new D7000 body with an array of 2-3 year old D7000 bodies that had been in regular, daily use for the entire period of time in order to be able to observe any differences with the unaided eye. Even in such a situation, I think you'd be hard pressed to actually see any differences.
