I was recently looking to purchase Game Of Thrones Season 1 on 4k Blu-Ray however after doing some research it seems that the first season was actually all shot in 1080p so the 4k blu ray discs are is just upscaled versions of the original content.
I was wondering if letting a TV upscale 1080p content to 4K would be any lesser quality than buying the 4k Blu-Ray discs of the upscaled 1080p content.
