So just switched from Doom Emacs to GNU emacs (means I am newbie to Emacs at this point). Till now very positive about emacs. Done many things, just want to customize start screen. So I read the README.org, & see the parts for atleast having the dashboard. So, from here went to set the title from this line
(setq dashboard-banner-logo-title "Emacs Rules:)")
& set the banner (I think it is the logo)
(setq dashboard-startup-banner [".emacs.d/banner.jpeg"])
But both the things are not setting, the centering works, also the recent files & folders also works (didn't set any agendas or bookmarks so can't confirm both) but the logo & the title is not setting, so here is the relevant part of the init.el file

(require 'dashboard)
(dashboard-setup-startup-hook)

;; Set the title
(setq dashboard-banner-logo-title "Emacs Rules:)")
;; Set the banner
(setq dashboard-startup-banner [".emacs.d/banner.jpeg"])

;; Content is not centered by default. To center, set
(setq dashboard-center-content t)

;; To disable shortcut "jump" indicators for each section, set
(setq dashboard-show-shortcuts nil)
