How can i apply an externally loaded colorscheme from a different plugin

[flobilosaurus]

Im trying to write a plugin which at some points in time calls vim.cmd.colorscheme XY. It works as expected with build in colorschemes like darkblue or delek but only partly with externally provided colorschemes like tokyonight.

For colorschemes like tokyonight it works after UI is fully constructed and lazy has loaded all plugins but it does not work initially as part of the setup function of my plugin.
I tried a lot of different settings for my plugin like event, priority, modifying the config function to require the needed colorscheme but nothing worked so far.
Only when im registering an callback to the VimEnter event it works but breaks stuff in other plugins like lualine.

I tried to simplify the problem by just loading a non-standard version of colorscheme like tokyonight-day from my plugins/colorscheme.lua like so:

return {
	{
		"folke/tokyonight.nvim",
		lazy = false, 
		priority = 1000, 
		config = function()
			require("tokyonight").setup()
			vim.cmd.colorscheme("tokyonight-day")
		end,
	},
}

This does not work (at least on my machine). Can someone pls enlighten me?
