I don't even know what the hell SD Up-conversion means.
It means the standard definition image was enlarged digitally to high definition. Previously, season one existed on 1-inch analog videotape with an equivalent digital resolution of 704 by 480 pixels. Essentially, every original pixel of the digitized tape became four pixels through a process known as bicubic interpolation. It is now 1440 by 1080. They adjusted the color and contrast levels to match the new film scan as best they could and then they added fake film grain over it.

Oh, and to use this has a teaching thing maybe, how do you guys know. I see the screencap, and other than the turning of the head, they look exactly the same.
Well, other that the fact that it doesn't at all look like it came from a modern 4K/2K film scan, it's also missing 17% of the image the preceding shot of Riker has. So it's obviously the 2 second shot mentioned on the back cover.
