How to use parameters to get the minimum bandwidth?

[adream100]

My idea is, under the conditions of determined resolution and color depth, can we achieve the minimum traffic between the client and the server by choosing different algorithms? The purpose is to be suitable for different bandwidth environments.

For FreeRDP, I'm still using the familiar v2.x, here I choose the latest version: 2.11.7
The resolution is 1920 x 1080, color depth is 32 bits. The Server is Windows 10 22H2 and has been upgraded to the latest.

I've tried:
/network:modem|broadband|broadband-low|broadband-high|wan|lan|auto
The effect is not significant.

I also tried:
+compression /compression-level:0~2

The effect is still not significant.

I checked all the documentation of freerdp and found no relevant information.
I'm confused. Is it possible to significantly reduce traffic? Don't care about image quality loss.

basically just no parameter at all.
the protocol does bandwidth measurements and reduces to match automatically.
