A DVD has smaller resolution than 480p. DVD use non square pixels, I'm forgetting if there is a technical word for this. DVD has a different display resolution and stored resolution of the video. The DVD will store the video at 720x480 and then display the video as if it was 854x480. The exact resolution varies by region and DVD. When you watch a DVD you are watching a video that has been smushed and then stretched.
Also much of the stored DVD resolution is commonly black border bar because many theatrical movies are wider than 16:9. When you consider the black bar and the smush/stretch, you realize that the resolution you are watching is much smaller than 480p. 480p is defined by having a video height of 480 pixels. A common theatrical movie aspect ration is 1.85:1. To be 480p at 1.85:1, you would have a resolution of 888x480 and a common DVD has much less pixels than that.
Also DVDs commonly use a technology called interlacing which makes the video look like venetian blinds at high motion scenes on a modern television.
Basically DVDs were designed to be viewed on CRT televisions.
most modern media collectors are using Blu-Rays anyways
While it is true that Blurays have modern resolution. I don't believe that it has been widely adopted. People still buy DVDs more than Blurays. There is still a lot of people who only watch DVDs.
This shows that over 50% of new physical media sales in US were DVD as late at 2023. Bluray adoption is still not widespread and also the Bluray sales are even smaller when you consider people who use streaming services. Then you consider that when DVD was at its peak, streaming was not a competitor. This means that the number of total DVDs in circulation is much higher than Bluray. Collectors often buy from resellers. When people brag about their physical media collections, they are most likely on DVD, not Bluray.

i wonder if it's because bluray came along around the same time as internet streaming and internet piracy, so there are just way fewer bluray players out in the world.

some call them "woke pixels"
in short, DVDs, while much better than VHS, still look like ass.
