Many people are lamenting the apparent slow demise of Blu-ray. The image quality these players offer is much higher than that of streaming, featuring a bitrate that can go up to 128 Mbps in the case of 4K Ultra HD Blu-rays. Most streaming services are somewhere between 15 Mbps and 25 Mbps.
tbf that's just a setting/feature of streaming services, they are capable of uping the quality to match that of Bluray they just feel the demand isn't there which means there's a gap in the market
In Australia we now have 500mbit plans for under $100 a month, so it's definitely capable of going up to 4k blu-ray quality
Also 8k TV's are on the way out as well, it just looks like people are happy with the quality of video these days
