Discrepancy in Cookie Consent Options Across iOS 18.0 and 18.1 on Certain Websites

I've observed a discrepancy in cookie consent options between iOS 18.0 and 18.1 on some websites, such as www2.hm.com. On iOS 18.0, I see "Accept All Cookies" and "Only Required Cookies" options, whereas on iOS 18.1, the options change to "Accept All Cookies" and "Cookie Settings."

I would like to understand if this behavior is related to differences in how websites detect the operating system version (iOS 18.0 vs. 18.1) or browser changes within the iOS update. Has anyone else experienced similar variations in cookie consent banners, and could this be tied to differences in the user agent or website A/B testing for different OS versions?

Any insights or technical clarifications would be appreciated!
