When searching for a channel, there's a section called 'Latest Shorts from ___' and this section has a line/gray separator. A patch which either hides it or matches it's color with the value of theme patch. The line which is mentioned above:

Motivation

It feels out of place if the user has amoled theme patch applied or perhaps any theme applied given it doesn't follow the theme patch. Also, it feels like the gray separator patch isn't applied in search fully.
