Raster SVG export has poor quality

[TanyaEstevess]

Hello. I'm trying to export some raster data I have created into an .svg file format and the end result turns out blurry for all raster layers. Boundaries for feature layers are crisp. I have this in the Layout:

and end up having this after the export:

I use the export layout menu and have applied the following settings:

I prefer using svg because I am using it in a word doc that will after be turned into a pdf. I have found that SVG is the format that lesse loses image quality when exporting the word to pdf. 

Even the world topographic map baselayer is having issues and presents as blurry.

Is there anything I can do to have better quality when exporting my data? Thanks
