When I play standard HDR content on Plex, my TV displays the Dolby Vision logo at the top corner. Is this normal?

I am using a Plex server for self hosted content and I have some older videos with HDR, but they display as Dolby Vision.

I am using an Onn 4k Pro as my streaming device and a Hisense U7G (55U7G) TV.

I set the setting on the Onn to match the content because previously even SDR content triggered the DV logo.

The match content setting fixed the issue and now SDR content doesn't display the logo anymore. However, HDR content shows the DV logo when played.

It looks fine for the most part, but I am wondering this behavior is normal? I would assume the TV or device would use HDR for HDR, not DV.
