HLG is also HDR format which is used for Broadcasting mainly like Live channels..
If HLG LOGO is showing than its HDR singal only, And your TV is definitely shifting from SDR to HDR on Travel XP, like I said
Hybrid log–gamma - Wikipedia (More on HLG)
On the other hand I have to recheck on my TV, last time I saw it was HDR10

Thanks @alamodein for your help in clearing my doubts
Well good explanation...For me also its showing HLG now. And picture quality seems much better (personal opinion)
See screenshots

AFAIK HLG is not the perfect HDR/HDR10...As u said disabling the SDR to HDR should has to show HDR channels as HDR itself...I think travel XP 4K HDR channel is not having HDR originally...It's just upscaling to HLG...
Enabling SDR to HDR means upscaling the signals to HDR ...
Just a thought from me...

Yes bro, that's the HLG logo in the screen shot from the TV Pop-up notification is for HDR
Also picture setting changes automatically to HDR Settings in my TV once I switch to Travel XP
However I agree HLG is not good as HDR10 and far from Dolby Vision.
The reason:
HLG is mainly used in broadcasting channels specially Live content like matches due to dynamic nature of content which cannot be pre processed in production
HDR10 has fixed metadata and applies to whole content in video and thats why used for streaming or playbacks
Quote from the following link showing comparison between HDR formats
"The primary difference between other HDR standards and Hybrid Log-Gamma is that while standards like HDR10 and Dolby Vision are used for streaming or playback, the Hybrid Log-Gamma primarily focuses on broadcasting, i.e. it has been created as a solution for high-quality cable TV, satellite TV, and live TV"
Differences Between The HDR10, Dolby Vision, And HLG
An increasing number of manufacturers are introducing HDR enabled TVs and projectors. These devices display images with higher brightness

Right....
That I exactly say ..that confirms as travel xp 4K HDR is not true HDR but HLG only....Means close to HDR....
We can confirm in Disney+Hotstar app by playing any HDR content checking in stats for nerds...In these pictures we can find the difference of video formats between HDR and non HDR...Can u check these video formats of HLG and HDR?? If so we can confirm the exact video format of travel xp 4K HDR..
In my TV if I go to Signal Diagnosis under Advanced System>Help with Travel XP tuned..
I see following Information:
Video Format: 3840*2160p@50Hz
HDR:Yes
( I will put screen shot later)
So definitely its HDR signal. and like I said, picture Settings also changes from Dynamic to HDR
HLG is also a valid HDR format. Quality wise might not be upto HDR10 format. Simple reason, limitation due to live broadcast , compare to streaming or stored contents
