There is no ongoing flicker on e-ink displays. The display is absolutely stable with no flicker while you’re reading as there is no refresh. If you trigger a page change the page redraws the new image in a fraction of a second. It looks a bit like a fast cross-fade. If you are updating smaller regions of the screen it is fast enough not to notice. Scrolling would still be a problem as that requires a much faster refresh rate. Such fast refresh would eliminate one of the major benefits of e-ink which is the low power. If you were to refresh e-ink at 30-60Hz it would likely use as much or more power than an LCD.

There's a periodic full refresh to clear any "ghosted" pixesl, often at a user-definable frequency. This occurs only during a display update, so yes, as long as you're looking at static text, there won't be a flash. The trade-off is of pixel ghosting vs. flash. The more frequently the screen is fully refreshed, the less ghosting. In practice, I tend to set this value to about 20 refreshes for reading texts, and will frequently manually refresh the display when reading Web content in a browser where scrolling is more prevalent. For monospace (terminal) displays, the fact that each character tends to update in the same screen cell makes the ghosting issue less significant and noticeable. What happens is that the background gets somewhat greyer as text is read or scrolled, but there isn't the effect of strong imprints under the text as with graphic or typeset content. A refresh largely has the effect of brightening the background. Noticeable, yes. Annoying? Largely not.
