i don't think its necessary, if you follow the line pointing at the conveyors with the current version, says mk4, its gonna be red, if its blue then its not upgraded yet, not only that you can pay attention to the side, mk1s have pretty thin borders compared to mk2 and so on, another way is to just jump on the conveyor and pay attention to your speed, if your character is slowed down that means its a non-upgraded segment, you can even pay attention to the ores, they will be spaced out when they go through a slower conveyor and then a faster one.
