I don't buy that. It may look a lil different, but good calibration settings can give u a good base for a great pic.
Netflix looks incredible on the c1. Football still looks suspect. Im guessing cuz directv seems to only have 720p resolution
Yeah, a lot of normal broadcast sources are going to look iffy. One is resolution, like you mentioned, because you're honestly lucky if your provider even broadcasts in 1080P. But the real hit on quality will be compression. Even on streaming services, most broadcast channels are compressed to shyt. Those two along will be why you'll notice a big difference in stuff on Netflix that's just plain 4K, let alone something mastered in Dolby Vision.
And panels can actually have a huge difference in variance. Color temps can run cool or warm, backlights can vary in brightness/intensity, and the room itself can make a difference. Really, any preloaded settings are really more guidelines, as opposed to definitive.
