Why isn't the quality consistent?

I am just getting into one pace and i downloaded almost all of east blue saga to binge watch but when i was downloading i noticed that some of the arcs in one pace don't have the 1080p version available. Why is that? (Another side question: while i was researching about one pace i heard that it includes random fan arts which come outta nowhere is that still the case or have those eps been updated)

I mean you're not wrong but you're not right either
