This latest update from 14th Feb is 15MB. I guess that's the one you're asking about. If so, my phone was never prompted to "accept" the OTA update. It just updated by itself without my consent. But other folks have said it will forcefully update after declining 3 times. After update my phone was stuck in TWRP bootloop. But don't worry there is a perfect solution for that as well, if that's what happens to you.
Totally upto you if you wanna take the update or not, no changes on the user experience at all.
