Those refer to different policies/different scanning components.
IPV refers to the external IP reputation services (external spamlists), in this case IPV:NLI means that the IP was not found in any of the external lists. IPV:CAL would mean that the address was allowed because you explicitly added it to a safe sender policy in the connection filter, regardless of the reputation from external sources.
SFV refers to processing by the Content filters defined for your tenant. In this case, SFV:SKN means you have added an exception in your content filter.
And yes, IPV:NLI means it still gets scanned by all other components.
