“TCQ and non-TCQ photographs can look identical to each other.”
(Often there is no visual difference at all.)
There are two common situations in which this can happen:

A copy of the photo that does not have that viewer alert cannot qualify as TCQ—
— while its identical twin that does have the viewer alert can qualify as TCQ.
