I understand that screen resolution is the number of pixels measured horizontally and vertically. Then the size of the screen is used to calculate the PPI. But if my screen resolution is only 2796×1920, how would I be able to view any video in 4K?

Through uniquely human ability called bullshitting. Also known as lying without directly lying. This allows someone to make a claim or statement that is believable enough so that the other person believes the statement to be true, even if it is false.
If I have a single pixel. A 1×1 display. I could downscale a 4K video and display it on that single pixel. Does that mean my single 1×1 display can display 4K video? Sure! If I’m bullshitting. In reality, no, it does not display a 4K video at 4K resolution.
In this same way I could say that I have a 10-foot vertical jump – If I can “downsample” a foot to be an inch.
An iPhone can shoot in 4K, and can playback 4K video, but it’s display is not 4k. Leveraging our innate ability to bullshit we can now *sell* someone something. “You want to watch that in 4K on your iPhone right? Better pay for that mega-super-primo plan otherwise you’re going to be missing out on all that great 4K video!”. This may not be 100% false, newer iPhones can downscale and playback 4K video, they are bullshitting you a bit if they get you to believe it’s better than video at your native resolution and a similar bitrate*.
* I’m kind of excited for someone to school me on the pro/cons of resolution vs bitrate above a display’s native resolution.
