From what I understand, TN1 SSE is from the 35mm LPP Film print, 4K77 is the same thing except it uses Technicolor and other prints, which means 4K77 is like the superior version compared to SSE
My question is, is SSE more accurate to what an older copy of the film looked like, and then 4k77 is what it likely looked like, brand new in a 1977 theater? Just wondering the difference between the two and why they have different color grading. Hope one can clarify. Thanks.
