There is still a market for Blue rays for precisely this reason, compression does a lot of harm to the image and streaming services often run at 1/4 or less the bitrate. There is also the sound compression as well which is very heavily done on places like Netflix, presumably because their intended audience is watching on a tablet or a low end smart TV that has terrible in built speakers but if you have reasonable addon speakers and especially surround sound the average has clearly gotten worse. The effect is very dramatic on Youtube and Twitch. Twitch has its ~6mbit/s limit and Youtube limits 1080p to around 10 mbit/s and 4k to about 18mbit/s which is well below the blue ray standard bitrates for these resolutions. You can't even override it with a better quality upload as it always compresses the Video to its standard bitrates. It shows up a lot in game footage where grass often becomes a smudge. The somewhat manipulative use of this recently has been DLSS and FSR. These two technologies effectively hide really well within Youtube's compression, while using them they introduce noticeable artifacts but once compressed by Youtube they largely disappear and appear almost identical to the original image. Soft images due to Temporal Anti Aliasing and reduced resolution also appear relatively normal on Youtube, they just hide in the impact of the compression. These defaults for ADSL levels of performance of the internet are quite harmful to image and sound quality across a range of services and while those companies might not want to pay for more bandwidth we as customers should want better bitrates for when we play it on devices capable of showing and producing better.
