YouTube Layout: Change the number of videos per row displayed on the homepage BUT NOT channel pages

I would like to be able to view 4 videos per row on channel pages, but only see 3 per row on the homepage (the thumbnails and text is too small for me otherwise).

[I found this prior thread on how to change the number for both the homepage and channels](https://www.reddit.com/r/uBlockOrigin/comments/1jwrggz/fix_for_the_youtube_layout_change_the_number_of/), would I be able to change or remove something from this to allow this filter to only affect channel pages, or is there something else I would need to add?

Thank you.
