stream frame size wrong detect

[ghost]

Some youtube servers sometimes for some videos by unknown reason publish wrong video properties. for example YT says it has FullHD 1920x1080 video resolution, allow to download the video stream, but actually stream has only 1600x800 resolution or 1920x800, this apply for mp4 stream, but for all stream formats. Is there a way to detect it correctly before downloading,
Example video which has 1920x1080 but downloading as 1920x800
https://www.youtube.com/watch?v=lfwjzNB--5k

Can someone explain that?

For provided example URL there are three 1920x800 formats:

137          mp4        1920x800   1080p 4062k , avc1.640028, 30fps, video only, 37.71MiB
303          webm       1920x800   DASH video 4723k , vp9, 60fps, video only, 43.23MiB
299          mp4        1920x800   DASH video 5510k , avc1.64002a, 60fps, video only, 64.98MiB

that all downloads as 1920x800 each, so you are wrong:

    Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x800 [SAR 1:1 DAR 12:5], 65 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc (default)

    Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x800 [SAR 1:1 DAR 12:5], 107 kb/s, 59.94 fps, 59.94 tbr, 90k tbn, 119.88 tbc (default)
