Q: Why -F is not listing all available video formats on Hotstar (for PARTICULAR TV show, "Siya Ke Ram")? It has 1280x720 video also, which was not listed in result of "yotube-dl -F".

take any video link of this show (of any episode):
e.g. "https://www.hotstar.com/tv/siya-ke-ram/s-402/janaks-daughter-sita-arrives/1000076668"

I run below command (On Windows):
youtube-dl -F "https://www.hotstar.com/tv/siya-ke-ram/s-402/janaks-daughter-sita-arrives/1000076668"

I get below result: (It has 1280x720 video also, which was not listed in result.)

I know that, It has 1280x720 video also, by using firefox plugin "Video DownloadHelper". "Video DownloadHelper" list 1280x720 video also apart from rest of the results, which I am able to download. But I wish to do it using youtube-dl as it has 326 episodes.

The reason for this is Hotstar changed the way it addresses URL's, example, in this case, if you download the episode of this show, which was before 2018, and not rebroadcasted on TV recently, they're addressed as:
Example:
Episode 1- Siya Ke Ram: Public link: https://www.hotstar.com/1000076668
Stream URL (best quality chosen: youtube-dl -f best "https://www.hotstar.com/1000076668"):
https://staragvodweb1-vh.akamaihd.net/i/videos/plus/skr/1/1000076668_,16,54,106,180,400,800,1300,2000,3000,4500,_STAR.mp4.csmil/index_7_av.m3u8

See that?
the numbers in bold mention the following bitrates (in kbps)
0. 16kbps

1. 54kbps
2. 106kbps
3. 180kbps
4. 400kbps
5. 800kbps
6. 1300kbps
   7. 2000kbps (720p video)
7. 3000kbps (900p video)
8. 4500kbps (1080p video)

I've stated with 0 and not 1, because this tells the index to which the player should give.

Hotstar prefers delivering the video in 720p if not reoptimized for 2018, hence index_7.av.m3u8
If you want better, 1080p video: change index_7.av.m3u8 to index_9.av.m3u8,
