Unity, do I need to change shaders for a mobile game (2d)?

Question

Shaders

Good day. I came across an article on optimizing unity games for mobile, where one of the points was to replace standard shaders with mobile ones or with your own. After a couple of articles, I figured out a little why they are needed at all, but I didn’t fully understand whether something needs to be changed if the game is 2d, sprites + 2 particle systems. For systems, I changed the shader to Mobile / Particles / Alpha Blended, but do I need to replace / add anything else?
I went to the Project Settings -> Graphics, there is a standard list, I googled the names of the shaders a little, and as far as I understood for 2d, you can replace all this?

Шейдеры нужно менять, если они на мобилках тормозят. Если игра летает, то делать ничего не надо. Подобные решения надо принимать исходя из данных профайлера, а не ответов на тостере.
