Before I start typing my wall of text, I'd better mention that this relates to the OCUK Nebula (google play lists it as unknown A721) tablet (new, not used or reconditioned).
Long story short as I mentioned there wasn't any sign that the tablet had been rooted by the original manufacturer since there was no superuser app in the list, and I only found out that it was rooted after I ran a game and I got booted back to the home screen with an illegal access detected, game cannot start message and some of the idiots on the play store have rated the specific game one star because of the error with a majority mentioning they had rooted devices, and I remembered that the game includes anti-root technology to stop cheating and I wasn't sure why it would think it would consider the device I'm using to be rooted.
I did do some googling and the youtube videos that came up in the search only mentioned that a superuser or superSU app would be present which isn't the case here, but one mentioned that using an app called terminal emulator can confirm a root if you enter su into it and the $ sign on the line it is entered into changes to a # on the second which even if you don't get a request to give terminal emulator super user privileges confirms that the device is rooted, so that is what I did and even though I didn't get any notification the change from $ to # in the terminal emulator was confirmation enough that I'd received a rooted device.
I did do another search on how to de root the device, but I'm not sure if any of the already posted on the web methods like using the complete unroot function in superSU will work considering there's no information on how it was rooted to begin with (however, I might just get this tablet out of android 4.0.4 and up to something that doesn't drain the battery as fast as a vampire drains blood).
