As expected, unsee or misread expression of disgust (4,6)
I believe the answer is:
sure enough
'as expected' is the definition.
(synonyms)
'unsee or misread expression of disgust' is the wordplay.
'misread' indicates anagramming the letters.
'expression of disgust' becomes 'ugh' (I've seen this in other clues).
'unsee'+'or'='unseeor'
'unseeor' with letters rearranged gives 'sureeno'.
'sureeno'+'ugh'='SURE-ENOUGH'
(Other definitions for sure enough that I've seen before include "Having sufficient confidence" , "as you'd expect" .)
