Image Capacity Difference

I have both a D7100 and D7200. Each are equipped with identical 32 GB SanDisk Extreme Pro SD cards, two in each.
Normally, after formatting the SD cards, and the cameras both set up for "JPEG Fine L" (or however it is supposed to be), the display shows a total capacity of "1.3K" images.
Today, the D7100 came back from Nikon where it had undergone some "minor surgery". I replaced the two SD cards, formatted the cards, and also -- in both cameras -- changed the settings to "RAW" for card 1 and "JPEG" for card 2. But, after doing this, including formatting the cards, the D7100 shows a total capacity of 589 while the D7200 shows 596.
Why would there be any difference at all between the two cameras?

Different cameras, different firmware.
The minor surgery might have included a software update which is a slightly different size than the one in the other camera.

Hadn't considered that. The "minor surgery" was replacing the main board and likely updating the firmware. However, I'm not understanding how that would affect how many images would fit on a formatted SD card.

Noise level,of difference.

Not a significant difference.

Did you verify the "JPEG Fine L" setting on the repaired camera?
Maybe the service center changed it for testing?

The number of JPEG is pretty much an estimate as the camera can't know how much it can compress an image until it has the image. So different firmware may do the estimate a bit different.

Yes, I went into each camera and confirmed the settings.

Makes sense

The difference between 589 and 596 is trivial. Even a small difference in the compression algorithms could account for it. Especially true if raw lossless compressed or raw lossy compressed.
