So, I tried looking at pictures of the actual miniature to look for clues, but even with the high quality pictures, the ovals weren’t showing up, so I can’t tell from that either. To illustrate my point about the CotF box picture, though, if you look at the picture of Nihilus here (this is not the CotF version): https://starwars.fandom.com/wiki/Darth_Nihilus
it is difficult to tell that there are 3 ovals on either side. It looks like 2 to me. But that picture is a high enough resolution that you can zoom in to it and tell that there are indeed 3 ovals on each side. That’s about all I have to illustrate my point. If we had a high resolution picture, it’s possible that the 2 ovals could actually be 3. The available pictures are just too blurry to tell for sure, in my opinion.
