I'm not sure what you are trying to accomplish. JPEG images are normally stored as YCbCr and not RGB.
You can reduce the jpeg_quality if you want to reduce the file size.

It could save some disk space. I tried already several image format settings in the mapproxy yaml config, but it seems to affect only the png files. The jpegs I inspected after seeding had 24 bit.
