Are iPads on iOS 14 that can be upgraded to iOS 15 worth more?

I have an iPad I'm thinking of selling. I know downgrading is a pain, and I heard of the controversy of the now-suspended CSAM. Am I likely to get more money from buyers if it's on iOS 14 than 15?

Very unlikely to be able to get more money unless it's a buyer specifically looking for iOS 14 (developers often want that for testing their apps). Even then, the difference would be a very tiny amount. it's not as if iOS 14 devices are in huge demand and limited supply.
