This is how the shot appeared in the original episode;
And this is how appears in the Remastered version. They've zoomed in substantially, and the pretty decent matte-painting has been given a bit of an (unnecessary, IMO) CGI makeover, adding a monotrain and extra people milling around in the background.
Although I don't want to beat a dead horse, I would like to add that the original matte painting was much wider than what we saw in both versions, where already the TOS frame was just one third of a wider picture! (Allan Asherman's Star Trek Compendium
had a b&w shot of the matte painting revealing the "missing" two thirds to the left).
Had the TOS-R producers been aware of that we might have seen more of the "authentic" Eminiar VII skyline, possibly during the skyline beauty shot after Kirk's landing party had been disarmed.
