AT&T TV Now customers can subscribe to the Movies Extra Pack for $5/mo to get Hallmark Drama, Hallmark Movies & Mysteries, MTV Live, Smithsonian Channel, HDNet Movies, MGM HD, Shorts HD and Crime & Investigation (ironically an A+E Network ). If you get Movies Extra Pack on D* you also get Sony Movie Channel (this is not available on AT&T TV / TV Now.) Only the TiVo Stream 4K runs Android TV and it is a lightly customized variant. The customized/unified TiVo GUI is actually an exclusive app called TiVo Stream. The Silver TiVo button on the remote will open this app. TiVo's standalone hardware for OTA and cable users along with the cable operator branded TiVo set-top-boxes use a proprietary OS which require apps to be developed specifically for it. The actual TiVo hardware using the proprietary OS lacks the new apps like Disney+, HBO Max & Peacock. It used to carry HBO Now which was updated along with Amazon & Roku to just "HBO". HBO Go was removed after it was discontinued. T-Mobile & Dish most likely want the devices to be usable if the end user decides to cancel their TV service. AT&T on the other hand initially had Osprey locked to where you have to have AT&T TV or TV Now. Recently AT&T changed that and now there is a basic blue screen that lets you access your apps or the device settings when your account is inactive.
