My mantis came in today, I did a nice slow drip acclimation. The white parts on opposite ends of the telson are scaring me a bit, is this shell rot?

That is normal.

Shell Rot looks like a 'Burn' or 'Scaby' looking.

Thanks! Good to know. I thought the white spots were she'll rot as well.

Mine has the same features. Perfectly healthy!

So why do some have the white parts? What causes this? Just a common aesthetic trait that is passed around?

Could be related to age/physical animal size.

O.scyllarus tend to have an almost uniform pattern in comparison to other smaller smasher species which can be vividly different and yet still the same species.

The peacocks tend to transition from a light brown/rust color when smaller into a deep darker green when larger (at least in my experience from those I've had), they do vary slightly overall but they have a "general" pattern amongst them all.

Smaller specimens around 4inchs tend to have this white on the uropods.
Larger specimens around 7inchs (as per my photo) tend not to have this on the uropods.

Good general rule of thumb I've found when it comes to not knowing what shell rot looks like but worried if peacock has it in a certain spot, is to look at the symmetrical opposite side, if it is the same marking then it's likely natural, if there is nothing there then your original guess might be accurate or something else all together.

Iirc O.Scyllarus colors also vary based on the depth (spectrum of light plays part here) they live in. Ones found deeper tend to be more orange/brown, and moving up the color usually is around grey-green. I don't think there's any confirmation or data that specifically payed attention to this but I've heard it somewhere and I've seen it impact specimens of neogonodactylus.

I'm not sure whether growth/size counts, probably the shading of the specimen may change as bigger usually makes colors stand out more, but I've seen full 6" specimens that were brown, greyishblue, to nearly neo green.

The white on the tail is beyond me. Personally I've only seen two specimens (in person) that had white (one orange, 4", one "neon" green 6") but I know its pretty common.
