Is there a way to ffmpeg or maybe another tool that detects if video has

For instance if I am offered two downloads one 720p and one 1080p. I
have sometimes the impression that the 1080p is just the 720p converted
to 1080p (not significant better quality). And thus just uses more
space.
I am not sure if I am using the correct terms here, I do not do to much
with video nor audio. However I am getting more and more annoyed with
the presence of 2K videos claiming to be 4K and 480p/720p claiming to be
1080p.
