blue-blooded

I'm a little stuck... Click here to teach me more about this clue!

'noble' is the definition.
(similar in meaning)

'smeared viscerally by dismal' is the wordplay.
'smeared viscerally' becomes 'blooded' (blooding is a kind of smearing. I am not sure about the 'viscerally' bit.).
'by' means one lot of letters go next to another.
'dismal' becomes 'blue' (I've seen this before).
'blooded' put after 'blue' is 'BLUE-BLOODED'.

Can you help me to learn more?

(Other definitions for blue-blooded that I've seen before include "Aristocratic" , "Born high" .)
