I haven't explored all of the entries, but the DISPLAY CK does show the same color bars. There is another secret menu for "Photo studio mode":
that's cool, wonder how you managed to take a real screenshot of it. the only useful part of it I've found is the dust delete data test which shows where dust is on the CMOS. Depending on how big the partile is will depend on the colour that the little ring will be. Before cleaning my sensor I had some green and red rings but now only those two stubborn blue ones.
I'm interested in what that 'administration menu of yours does!
