How do I know for sure what OS I reinstalled from Internet Recovery?

I followed the instructions to erase the hard drive and then reinstall macOS on my late 2011 MacBook Pro (High Sierra) so I could sell it. I clicked on Reinstall MacOS and it seemed to be going okay, but obviously I did something incorrectly because I got this message: "Could not create a preboot volume for APFS install." I posted my dilemma and at someone's suggestion I did the Option + Command + R and it used Internet Recovery to run the installation from Apple’s servers. Since I was running High Sierra before erasing and my software updates only showed up for iTunes and one other app, can I assume that High Sierra was re-installed? Should I log on through the welcome page to see what it is running? If I do that, should I then erase again and reinstall again?
