I hear you. And as always it depends on what the collector wants right? Screen accuracy or idealized. In my Star Wars and Indy props, I tend to gravitate towards the former. But for comics cosplay/props, I tend to idealize. In this case, the idol I own is the Belloq and it had no pupils, which looked off to me. So I added the dots and I much prefer it, as I wasn’t going to carve pupils into it. Plus it gives me the benefit of being screen accurate to the stunt. .Personally I think the idol should be all metal with indented pupils in the eyes. People get hung up with this prop because of the different versions used in the movie and a fan-obsession to have whatever looks more like "the prop" as opposed to what the object is supposed to be like in the story, which is what's actually important (at least to me it is). Problem though is that there are a bunch of different versions of this particular prop and that always throws conversations about it into chaos.
The only reason there is a version with glass eyes is because of a deleted beat where the idol was meant to look haunted and follow Indy with its gaze. Remnants of this still exist in the movie but it's nothing but an abandoned idea that they didn't follow through or it'd be much more obvious and the idol design more consistent throughout the scenes. Belloq's idol, whether it actually had concave pupils at any point or painted on ones, it does have pupils, which is what matters. The painted dots however are just a cheap way to trick the camera and not what the idol would've actually looked like in the fictional world it inhabits. Bottom line, if the glass eyes are an abandoned idea and the painted ones are quick workaround, neither of them is really the right look for the object. Most likely, it was always meant to be a solid gold piece with carved in pupils, but instead, everyone always goes for behind-the-scenes concept approximations, which makes finding story-style idols much more difficult.
The Dark Matters one has the look you want I think, though subtle.
