That page says it affects *some* cameras with serial numbers between 501001 and 546561 and *no* cameras with higher serial number. The link on that page gives a PDF with a list of cameras in the range which are not affected.
Only *recalled* cameras got the dots, not the ones above the affected serial number range.
