In some cases, the artifacts of the medium can be desirable -- especially when consuming media that was created with those artifacts in mind.

Take a look at pixel art on CRTs vs LCDs [0] and Toy Story on film vs. digital [1].

What most people think of "vinyl sound effects" are not what the "warmth" is about. That's just playback instability and waveform aliasing caused by shoddily made players.

Good vinyl is "wait, did we have this back in 1970s" good(the recorder yes, the player not exactly, hence the prevalence of vinyl sound effects)

With vinyl warmth is the result of a deliberate process. Professional masters are done specifically for vinyl to accommodate its quirks which truly changes the sound. They have to clamp down the dynamic range and tidy low frequencies or the needle will skip. Recordings with lots of busy high frequency information also can’t be physically captured properly in the cut. The resulting master is a version that purposefully doesn’t have as many volume swings and harsh highs or boomy lows. Smooth, cohesive, warm. There are also track ordering strategies which is why ballads tend to be at the end of one side and the high energy stuff up front where there is “resolution” to serve it. The mastering engineer is adjusting each song with all this in mind.
