I am debating between purchasing the Sony A9F in either a 65 inch or 55 inch. My viewing distance is approximately 7.25 feet to 8.5 feet (from where the TV will mount to my seat). I am curious peoples view on which size TV is the right size given 75% of what will be viewed will be regular 1080i...

I have to replace my TV in my new place with a viewing distance of about 7 feet. I'm trying to decide between 55 or a 65 inch 4K set with viewing angles of 32 and 37 respectively. THX seems to recommend 40 degrees as ideal but everyone already seems to think that my 60 inch set looks too large...
