Will the TV not being calibrated account for the varying picture qualities he experiences on different discs? It seems if the TV needed to be calibrated the bad picture quality would be consistent no matter the disc.

I haven't read reviews of the PS4 but the PS3 was the benchmark for Blu-ray for a long time. My son-in-law uses a PS3 for movies and Avatar looked like a video game because he keeps his TV set to 240 or one of those not really appropriate for BD.
