it typically offers better video processing and upscaling, more accurate color reproduction, cleaner gradients, and superior HDR handling (including dynamic tone mapping on some models). Many also support Dolby Vision from UHD Blu rays, which the PS5 does not.
It won't show on a bad screen that much, but a dedicated player will squeeze out more of the disc.
No upscaling as it's not necessary. (But better players have better 1080p to 4k upscaling too, as the algorithms are more sophisticated, e.g. edge-adaptive scaling, temporal filtering, etc.)
First, the player performs MPEG-4 HEVC decoding, reconstructing full video frames from heavily compressed data.
Once decoded, the signal is still not in a display-ready format.
UHD Blu-rays are almost always encoded in 4:2:0 chroma subsampling, meaning luma (brightness) has full resolution, but chroma (color) is spatially reduced. so one of the first steps in the pipeline is chroma upsampling (chroma reconstruction). After that, the player applies color space conversion and output formatting, usually converting to a HDMI-friendly format like YCbCr 4:2:2 or 4:4:4.
HDR handling is sometimes done on the player.
The tv is doing a last stage processing that is fine tuned for it's display like contrast enhancement.
There's a bit of misinformation here. At the end of the day, a blu-ray player is reading information from the disc and passing it onto the TV digitally - one player or another are going to do that identically. One can't have 'better color' or anything like that.
HOWEVER, there is an exception: Feature support. For example, not all blu-ray players support 4K blu rays. Not all players support Dolby Vision.
If you try to play a 4K blu ray disc in a non-4K blu ray player, it won't function at all (won't read). If you try to play a disc using Dolby Vision in a player that doesn't support it, it will fall back to HDR10.
But assuming 2 players both support the features a disc uses, the end output will be identical.
There's also upscaling, which some players can do differently.
the final output is not guaranteed to be visually identical because parts of the processing pipeline (chroma reconstruction, tone mapping, scaling, and output formatting) are implementation-dependent. There is a spec, but multiple processing stages are not strictly defined to be identical. Higher end players also use a HDR Optimizer and the ps5 does not, which is visually noticeable.

Knowing nothing about the topic: what kind of processing and upscaling happens when I play a 4k movie on a 4k TV?

I hope that helps
Most blu-rays are 1080p, not 4K. The latter gets marketed as "UHD" and sold in a black case, to contrast the blue case of traditional FHD blu-rays.
