see explanation @cones. The story is a little more accurate.

What the person in question does is play the role of the judge. Depending on the circumstances, you may have sympathy for that. This way I understand the downloaders, but it’s still wrong. For example, I would like to watch movies in 4K in the highest quality with Dutch subtitles. What do you need for this:
Blu-ray UHD player. Prices still start at 150 euros years later. New discs cost at least between 15 euros and 20 euros. Streaming can mess with bitrates and therefore quality, so unfortunately it is not taken into account. You also remain limited in terms of supply and this changes regularly.

But then it has not yet arrived. You have HDR, as there are different technologies. I think Dolby Vision is the most comprehensive. But the joke is: It doesn’t guarantee anything. Technically there is scope to allow the shots to go up to 10,000 nits, but in practice the maximum is already at 1,000 to 4,000 nits.
Not that it matters, my OLED doesn’t reach 1000nits, let alone full screen.

Then you also have to mess around with real/fake 4K: a lot of the footage is upscaled to 4K, or because the original was recorded at a lower resolution, or because CGI was rendered at a lower resolution and rendered again “too expensive”.

And then you have to make sure that your discs have Dutch subtitles, with the English versions, this is sometimes missing, as the French one is.

In short: I understand downloaders. It has sickened the market to the point that even with genuine demand it becomes more difficult and too expensive. Most of them don’t care much about quality and aren’t critical of what they offer, so they gush (hence complaining). I don’t think it will ever improve.
