To be fair, resolution is not enough to measure quality. The bitrate plays a huge role. You can have a high resolution video looking worse than a lower resolution one if the lower one has a higher bitrate. In general, many videos online claim to be 1080p but still look like garbage because of the low bitrate (e.g. like on YouTube or so). If you go for a high bitrate video, you should be able to tell pretty easily, the hair, the fabric, the skin details, the grass, everything can be noticeably sharper and crisper.
Edit: so yeah, I agree with you, because often they are both of low bitrate…
