I was looking at the iPads at Costco this week just for fun. I played with all the sizes and bezel colours present. So this ensemble was the mini, the pro (2 sizes), regular and the new cheap regular.
The one that was the most comfortable (enough that I paid attention to it on separate days) to me on that table was the 64G iPad Pro 10.5 with the white bezel and gold back. Item 2408901, I believe the iOS version on it was 10.3.2 (maybe 10.3.3 I forget). The difference is subtle, but I'm pretty sure the black model next to it had a different screen or driver. There is no way to tell what is in the box. Just saying that this one particular one that I was holding, I think some of you would have found it serviceable. The rest of them, no.
