Same. Even the lackluster selection that is Canadian Netflix covers like 99% of my entertainment needs, with almost all of the remaining 1% being achievable via iTunes Digital Copies. In fact, the few Blu-rays I've purchased have mainly been because they came with an iTunes Digital Code and were cheaper than a direct purchase on iTunes. I used to buy a few movies a week in the pre-Netflix days and streaming just completely cratered the need for physical media because the cost and convenience gained was unquestionably well worth the "almost no one notices anyway" drop in quality.
4K itself will take off but it'll mostly be streaming; the UHD Blu-ray format is definitely not going to meaningfully take off, especially with costs being what they are now.
