Sonnet 130 is in more of a humorous fashion. In short, Shakespeare is saying his mistress' beauty is not that of a goddess, and she cannot be compared to the beauty of one.
The mistress in Sonnet 130 is portrayed in an unconventional way for the time, as the poet does not use traditional flattering language to describe her beauty. Instead, he opts for a more realistic and satirical approach, highlighting her natural flaws and imperfections. This makes the sonnet stand out from traditional love poems that typically idealize the object of affection.

Imperfect. Ugly
Shakespeare says: 'My mistress's eyes are nothing like the sun'
A bad smell.
In sonnet 130, the speaker mentions that his mistress's cheeks are not as red as coral. He is highlighting the honesty in his love by comparing her to realistic, ordinary things rather than using exaggerated, flowery language.
An example of hyperbole in Sonnet 130 would be "And in some perfumes is there more delight / Than in the breath that from my mistress reeks." The comparison of a mistress's breath to a foul smell is an exaggerated and intentionally unrealistic statement for effect.
His mistress in this poem is his beloved. That is not a particularly obsolete meaning.
