Tvs especially now tend to have a lot lot lot more post processing options (for better or worse) most tvs now have AI up scaling which on high end tvs can make lower resolution content (like dvds) look noticeably better.
They also have motion smoothing or what ever the specific brand calls it. Basically increasing the frame rate of something by generating additional frames to put in between real ones. This is pretty universally accepted to be absolutely horrific amongst people who actually care about how they watch things.
Tvs also tend to have a lot more input output options, and will come with (again for better or worse) a lot of smart tv apps.
