From a quick check, that link appears to just be to fixtures, not necessarily matches for which TNT have broadcast rights.
Sky's 4year contract with Sanzaar expired at the end of last season, so currently the rights are up-for-grabs. Their interest was historically for the internationals, with the club games a brucie-bonus freebie. Many fans appreciate the club games (I'm one) but commercially their value was less.
With ITV taking a 4year FTA deal for the summer (& autumn, but irrelevant for this argument) tours, that leaves the South African series in 2026 & The Rugby Championship in 2027 as, hopefully, worth Sky's interest. Otherwise Premier Sports were apparently sniffing around Super Rugby and I dare say would take the club games on. I hope they don't, but some would argue they're better than an online-only arrangement via Rugby Pass.
