Just comparing two HDTV rips I have of Ghostbusters II (a 1080i one and a 720p one) assuming they both used the 2005 master and I noticed my 720 version (which is sourced from another 1080i HDTV version) has a slightly different colour grading altogether from the 1999, 2005 and 2014 masters. Just looking at the first establishing shot of the museum, it’s slightly brighter/less brown than 1999 and 2005 but not as blue as 2014. The frame is as wide as 1999 but slightly less image on top and bottom compared to the 2005 1080i HDTV I have. I don’t know if it’s my eyes and the fact that it’s quite late in the evening and I’m tired but it looks different to me. The 720p HDTV I’m referring to is still out there if you look in the right places and was uploaded in 2011 if anyone wants to see for themselves.
EDIT: According to this great site (https://www.theraffon.net/~spookcentral/gb2_homevid_compare.htm) there was a DVD released in 2017 containing GBI & II and for GBII a 2010 HDTV master was used rather than the 2014 Blu Ray master and the screen comparisons used appear to be the same as the 720p HDTV capture I have.
