There is no reason to believe sighted people get tired of seeing it.
They can ignore the display if they want.  Sight is not necessarily
analogous to sound.  A stock ticker on a web page, if a screen-=-reader
constantly speaks the updates would be so distracting and interfere so
much with listening to other content that the page couldn't be used.  A
sighted person can simply not look at the ticker.

That's true to a very large extent. But sighted people are quite
sensitive to visual movement. So if the stock ticker is mostly not
changing, there's not much distraction. But if it's changing all the
time, and especially if it's changing strongly or in unexpected ways,
then it can be really quite distracting.
