Well, I don't have a projector, neither a TV. My space is small.
I have a 4k 43'' LG monitor, so you understand that what I see in screenshots, I see on the blurays or UHDs too.
I always trust screenshots.
I view my blurays on my pc anyway, so the blurays themselves always look like the screenshots posted either at DVDbeaver, or bluray.com or caps-a-holic.
DVDBeaver review
It looks exceptional! Can't wait to get this!
Look at this shot for example:

The colors are much better and natural.
