So I went ahead and ordered the RhinoShield version of the the camera protector since I've been a fan of their screen protector from way back in the day - before tempered glass was a thing.
It comes in a pack of 2, and it does feel to me like a tempered material vs the usual PET or similar "traditional" RhinoShield film that I was expecting. The nice thing is that it definitely has all the holes cut out - vs most of the other types that I've seen that only has the one main lens cutout.
Other than the screen protectors, the pack comes with a cleaning cloth and some stickers for placement and dust (I didn't use the placement stickers), and a stiff card for bubbles.
Here's a pic of the other protector I didn't put on yet to show the hole placements. Overall, gives me proper piece of mind against scratching the camera glass. Not bad for about $15 (10 + shipping). If you are looking at their bumpers or cases, I think you can get free shipping if you spend a bit more - and they aren't selling this (yet) on ebay or Amazon that I could find.
