There are millions of android devices out there that have been abandoned by their manufacturers, so they might be omitting those details because the flaw hasn't yet been patched (and likely never will be.)
I'm not sure the image view has been seperated out into any of the play store updated components. None of the ones name and description suggest they'll have OS UI widgets like that.
Firat of all, some part of Android is updated via the store. So the Chrome vulnerability and system libraries were probably updated without you noticing.
Also, this started in May. Before it went public both Apple and Google had already patched some vulnerabilities. Latest round was in August/September.
