Mabye it's my connection but I think bkurays tend to look noticeable better than 1080 content on Netflix.
So I got with Blu-ray.
With that said.... I own like, 8 blurays so it's not something that happens often.
I'd rip it off the Blu-ray and toss the disc. Then probably watch it from Netflix.
I have Rogue One ripped to my PC. I own the Blu Ray as well as subscribe to Netflix. I will watch the lossless MKV every time.
I watch it on Blu Ray. I don't find any discomfort in putting a disc into my PS4. Right now I'm stuck with an old 2011 720p TV briefly though so I care less. (And the foliage on Dragon Age: Inquisition is hurting my sensitive spoiled eyes a bit, too, but that's neither here nor there.)
This. And it's not exactly inconvenient to get up and pop a disc in a tray...Blu-ray.
Quality > Convenience, always.
