You guys are misusing the word anamorphic - anamorphic 1080p would be 1440x1080 (with black bars in case of 2.35:1 movies), which would then be stretched to 16:9 for viewing.
I was totally going to call them out on that but you beat me to it Harmy.
EDIT: Crap! Now yoda-sama mentioned it while I was typing. I’m just slow.
