Am not blessed with a golden eye & I don't have megabuck equipments. I own a few BDs. My collection though hasn't grown much for the last couple of years.
Saw some BD rips courtesy of my co-worker, MKV files he said. We watched Prometheus on a 32" LCD display. The file was processed by a Panasonic DMP BDT-110.
With all honesty, I was quite impressed with the PQ. It's way better than DVD. Now, will it look the same on a larger display, I don't know. To an untrained eye, the differences might not be that noticeable.
But being a dinosaur, it's still physical media for this old chap. My technical knowhow is simply below average.
