So any email from hotmail.com, gmail.com, yahoo.com, etc. if there SPF or DKIM passes skip any further DNS tests?
Yes - there's no point in doing DNS blacklist lookups on yahoo, hotmail, and gmail as well as thousands of other mixed source providers. The IP tells you nothing. That's why I suggest the yellow listing.
I would skip test if they have SPF because spammers often set their SPF correctly.
