This returns a string with text '95b...', '...', '...'

This is three values.

You could either use strpos() on the raw string (as long as you know you
won't get partial/multiple matches). OR split the string to an array:

SELECT 1
WHERE
'95b5a221aeba15c' = ANY(
string_to_array(
'95b5a221aeba15c+fb4e7219ab898ce+b08586cb81059f9',
'+'
)
);
