Today, TV guide data within the broadcast (PSIP) varies wildly between ‘mostly complete’ to ‘spotty’ to ‘almost non-existent’. This is why we don’t use PSIP for any Tablo processes because it’s just not dependable.
TBD whether this gets wholesale improvements with ATSC 3.0 that would allow us to depend on that data.
It’s still very early days despite the hype and/or excitement from certain early adopters so any speculation about future products that would support this standard is just that… speculation.
