Yes hd word not in channel logo but that doesn't meant its sd feed
Channels having dual feed only need to mention sd or hd in the channel logo to differentiate
But in Dsport it having only one feed that's hd so no need to mention separately
k:
For further reference check below Tatasky dth hd Channel list Dsport hd available
DDF Exclusive - Tata Sky HD Channels & Services List Updated As On January 10th, 2018
And u can check any OTT platform like jio tv , Airtel tv etc...
Jio having Dsport hd though adtv not having original hd feed of Dsport so it's return Dsport in Airtel live tv
If u want i can share snap of both OTT platform
