In its review of Arrow’s The Apartment Bluray, DVD Beaver has posted some comparison images between it and MGM’s 2012 Apartment Bluray.
I’ve always noticed that the MGM Bluray is very slightly horizontally compressed or squeezed from the sides — faces are just a tad narrower than they should be. One comparison looks at a shot of an office lobby with a kind of global sphere on a pedestal. Obviously spheres are supposed be perfectly round, but the sphere in the MGM Bluray is clearly oblong.
(l.) Office lobby “sphere” (i.e., obviously oblong) as it appears in MGM’s 2012 Apartment Bluray; (r.) same sphere (not perfect circle but closer than MGM version) as it appears in Arrow’s new Apartment Bluray.
