Yeah, a lot of Super 35 material like True Lies and Spider Man 2 have all SFX shots done in the negative ratio shot at (be it academy or 1.66) as opposed to being hard matted to the theatrical (2.35) ratio. I know the FF versions of HP 1-2 are full 4:3 and I believe the SFX shots are too (I recall there being minimal cropping throughout when viewed alongside the scope version), while 4-7 are essentially the 1:78.1 framing side cropped to 4:3. 4:3 and HDTV versions of HP3 were cropped because while that one of course was shot S35 at 1.78, I believe WB used the matted theatrical print for all transfers because they were lazy or were on a mad rush to get out the DVDs ASAP.
