Engadget: Why your Avengers UHD BluRays aren’t actually 4K

With all these pixels, you might be surprised to learn that most movies and TV shows are still edited at a measly 2K, even for big budget extravaganzas like Aquaman or Avengers. Often, that shiny Blu Ray you bought or the 4K HDR stream you’re about to watch was actually artificially upscaled from normal dumb HD. So what’s going on?

The website 4K Blu-rays does a great job listing movies that are real or fake 4K.

I also love looking at details on IMDB in the Technical Specifications section.
