DistantHorizons.toml server side vs client side

In Multiplayer, I am confused about how the server settings can affect the client and vice versa.

For example, if I have

verticalQuality

verticalQuality

and

horizontalQuality

horizontalQuality

both set to "EXTREME" on the client, and "MEDIUM" on the server, the end result seems to favor the server's config. Because I also tested in singleplayer with the same world seed, and it looked much better meaning EXTREME was being used (as expected because singleplayer).

In contrast,

showGenerationProgress

showGenerationProgress

only works if I set it on the client, doing so on the server does not seem to do anything.

How about

generationRequestRateLimit

generationRequestRateLimit

and

syncOnLoadRateLimit

syncOnLoadRateLimit

? Which one gets priority over the other, the server's or the client's one?

On the wiki: "Distant Generation must be enabled on both server and client, otherwise generation won't be running; same applies for every toggle that has a server-side counterpart." This part also confuses me.

So is there a list of which features has to be set on the server, and which are client-only?
