Not necessarily. Given how most mobile UX design operates today, in most apps there’ll just be a single glassy hamburger button that opens a (much more legible) menu. You don’t need to read a hamburger button; you just need to know it’s there as a tap target.

Honestly, I think the iPadOS enablement of toplevel app menus + addition of multi-key in-app-menu-action completions to macOS Spotlight, is presaging an iPhone that has a physical “hamburger button” that opens the app’s menu [and pops open the keyboard, to quick-access menu items by key.] Then there’ll be no need for an on-screen hamburger button at all, other than as a fallback for old iPhones that don’t have the hardware button.
