Previously, Blue meant good-to-go and Yellow meant "activate ahead of time". That's likely still the case.
I have yellow ones, likely because I traded in Air Miles to get the Canadian Discounted tix, instead of buying directly from WDW. Last time I had these tix (Spring 2024), I had 1 blue (bought directly from WDW) and 1 yellow (traded in AM). So we had to go to Disney Springs anyway, but the cast member did do something with both tickets (yellow one and blue one).
What I'm trying to say is: Probably you're good, but maybe if you have time it's worth stopping in to Springs before lining up for a park.
