Yes! Currently, The Simpsons says "surround", and some other progs also. Better point out that I don't decode it myself, not something I particularly desire, so can't tell you directly!
The original Dolby surround is on some films from 1973 onwards (first - I think - was Ken Russell's "The Music Lovers" - I might be wrong!). But is standard now, films without it are rare.
Films from 1990s on are often in "Dolby spectral", still analogue, but with improved noise suppression, more closely approaching digital quality.
Note that, ther's often extra audio processing added by the tv companies, after the film analogue soundtrack and before transmission. Frequently a "noise gate", to suppress film hiss, but this can create strange "pumping", clip words off, generally sound odd, and completely muck up surround info if the 2 audio channels aren't "ganged together".
Sometimes, Dolby noise reduction decoding isn't done properly - or not at all - it can happen it's not switched in, or the decoder hasn't been lined up on Dolby Tone, etc, Then, you usually get muffled sound, although the surround info is still valid.
